You should ask your friends to teach you correct Bulgarian rather than their dialect.
"вървиме" is a dialect form originating from Sofia, or more correctly - the villages around it. The correct form for 1st person plural is "вървим".
As to the pronouns - you seem to omit them only if they are to be otherwise repeated. That's what I mean:

Аз искам да видим всичко! (here you omit it because it's again "аз") Ще правя много снимки. (here you don't because it changes) Ние ще спим на хотел и ще ядем в ресторанти.  (here you omit it because it's again "ние") Ше посетим музеи, църкви и джамии.

Actually, you need none. The verb conjugation carries this information. You need a pronoun only when you want to emphasize it:
We had lunch but I paid.
Обядвахме и аз платих. (I emphasize that I paid, it's good/bad/to be discussed)
Обядвахме и платих. (I just paid, it's a fact, but totally normal and expected)

Also, the pronoun can change the connotation:
We had lunch and I left.
Обядвахме и аз си тръгнах. (you somehow emphasize that YOU left, maybe the other person stayed)
Обядвахме и си тръгнах. (well, you just had lunch and then you left, nothing so special about it)

Otherwise it's amazing how well you actually use Bulgarian. You are right that the emotion is not communicated as you probably want it, probably because I would expect excitedness (this word did not pass spellcheck - is it wrong?) to come with longer sentences with a lot of "and".  Something like:

През пролетта ще имаме ваканция! През април няма да работя, а ще посетя Мароко с моята приятелка А. Ще пътуваме със самолет. Искам да видим всичко и да направя много снимки! Ще спим на хотел, ще ядем в ресторанти, ще посещаваме музеи, църкви и джамии, няма да мислим за работа, а само ще си почиваме! Нямам търпение!

The differences are minor - more or less connecting the simple sentences. But I think it would express more feelings like that.
