I would love to help I am going to post some basics that are on the blizzard web site
My  comments will be in CAPS

Here are some tips to help you gain Cenarion Circle reputation. 

Kill! Kill! Kill!
Kill Twilight Cultists for 1 reputation each until you reach Honored reputation. If you have a group or a helper you can kill them more quickly for faster reputation gains. This can take a long time, but the rewards are worth it. You can also collect Twilight Sets used for summonings which can enable more reputation gains. You can kill Twilight Flamereavers for 1 reputation point until you reach Revered reputation. 

MY GOAL WAS TO HIT EXALTED SO I KILLED TWILIGHT CULTISTS UP TO HONORED AND PUT ALL MY PAGES AND TWILIGHT SUITS IN THE BANK ( I HAD TO GET THREE ALTS AND BOUGHT THREE BAG SLOTS FOR EACH ON AND FILLED ALL THERE BAGS ON THERE PERSONS BY THE TIME I HIT HONORED AND THE MATS ALONE WERE WORTH PROB 1250G

Do Repeatable Quests


You can continue to repeat the Field Duty quests to gain reputation and badges. This will typically require a small group. The Field Duty quest gives 25 reputation each time you repeat it. After completing the initial Field Duty quest, you can select Combat, Logistics, or Tactical quests which give a related badge for each quest type. The completion of these quests gives 50 reputation. 
Combat badges will typically require a group to earn. It is possible to earn them solo depending on your equipment, skill level, and class. 
Logistics badges can be soloed. These are earned by gathering materials. Often you can buy these materials at the auction house. This requires gold to complete but allows you to trade gold for reputation which saves time. 
Tactical Badges typically require a group but can be soloed sometimes. 
If you turn in one Combat Badge, one Logistics badge, and one Tactical badge all at once via the Allegiance to the Cenarion Circle quest, you can gain 200 reputation. This is a good option if you're not saving the badges for any of the Volunteer, Veteran, Stalwarts, or Champion Battlegear. 
One of the most common methods of gaining rep solo is to gather Encrypted Twilight texts. These are dropped by Twilight Cultists mainly located at three camps in Silithus. There is also an Elite Twilight Prophet that drops multiple texts wandering in the region with a powerful escort. You need to collect 10 text for each turn-in for reputation. You gain 100 reputation per turn-in. You can buy these texts from other players in the region or on the auction house for quicker reputation gains. Many players get them on their own by killing Twilight Cultists. 
Another repeatable quest you can do is the Abyssal Crest turn-ins. You need to get three of them for each turn-in. You gain 50 reputation. You also get a bag of spoils that contains cool things and sometimes things you can sell at the auction house. You can buy Abyssal Crests on the auction house or get them by killing the &quot;tier 1 summons.&quot; You summon these monsters by gathering a Twilight Cultist set (Robe/Shoulders/Cap), equipping them, and clicking on the Lesser Wind Stone at one of the Twilight Cultist camps in Silithus. Some characters are capable of soloing these summons while others will need a group or another player to help them. 

THE FIELD DUTY QUESTS ARE GREAT FOR HEALERS I AS A DRUID COULD STEALTH SO I DID TONS OF TACTIAL QUESTS 1-4 ARE TO KILL TEMPLARS WHICH ARE PERFECT FOR YOU AND 6-8 WERE QUESTS WHERE YOU NEED TO FIGHT OR STEALTH INTO A HIVE AND TALK TO A GUY VERY EASY FOR ME AS A DRUID.
YOU GET GREAT QUICK REP THIS WAY THE PROBLEM IS THEY FILL UP YOUR BAGS BUT IF YOU LIKE THE ITEMS YOU CAN GET YOU NEED THE BADGES AND REP TO GET THEM WHICH ISNT THAT BAD TO DO.
Complete Quests
Many quests in Silithus can give you Cenarion Circle reputation when you complete them. Finish as many quests as you can. Some quests can be soloed, some require groups, while others may require a raid. Some players recommend waiting until the end of Honored reputation before doing the quests because at that point you can no longer gain reputation by killing Twilight Cultists. You can kill Twilight Flamereavers up to Revered. 
Cenarion Hold: Go to Cenarion Hold base in Silithus and complete as many quests as you can. These give you Cenarion Circle reputation. 
Travel around Silithus and complete any quests you can from the NPCs in the zone. Valor's Rest is another quest hub at the bottom of the region. 
Complete the quests for Ruins of Ahn'Qiraj 

ONCE AGAIN I PERSONALLY WAS GOIGN FOR EXALTED SO I HELD OFF ON ALL THE QUESTS TELL I WAS HONORED IF YOU ARE NOT INTERESTED IN THE LONG GRIND DO THESE EARLY BECAUSE THEY ARE A GREAT WAY FOR REP AND DECENT MONEY.
Try Abyssal Summons
There are increasingly powerful summons available in Silithus. First, you summon tier 1 summons (Templars), then use the items you gain to summon tier 2 summons (Dukes), and then tier 3 summons (Lords). At the highest level, you'll likely need a small raid to kill the monsters you summon. These monsters give reputation with Cenarion Circle when you slay them. The Duke summonings are the best for reputation gains. This is because the tier 3 summons only provide 25 more reputation while requiring a lot more components to summon them than the tier 2 summons. You gain the most reputation for killing the Dukes vs. summoning components required. 

THIS IS WHERE YOU MAKE SOME GOOD MONEY IF YOU GRIND THE CULTISTS OVER A LONG PERIOD OF TIME YOU WILL HAVE TONS OF SUITS USE THESE WITH YOUR TACTICAL BADGE QUESTS AND PREPARE TO RACK UP THE REPUTAION. THEN USE THE CRESTS TO SUMMON DUKES AND SELL THE SIGNETS FOR 20G EACH AND GET ABYSSAL PANTS OF STRIKING TO SELL WHICH ARE WORTH BETWEEN 50 AND 100G
Dungeon Crawl
Spend as much time as you can in the Ruins of Ahn'Qiraj killing &quot;trash&quot; monsters and bosses. This can allow you to quickly gain reputation with Cenarion Circle.

EASIEST WAY BY FAR TO GET REP IS TO GO INTO AQ20 AND KILL TRASH MOBS AND BOSSES AND HOPEFULLY GET SOME GOOD LUTE AT THE SAME TIME.


I HOPE THIS HELPS SOME
