Congratulations on buying one of the finest tractors ever built.

To answer your questions:

1. The best one is the original factory authorized shop manual. You can buy one from the Floyd County Museum at <!-- w --><a class="postlink" href="http://www.olivertractormanuals.org">www.olivertractormanuals.org</a><!-- w -->

2. While it is not a must, the Oliver parts manual shows all of the parts in an 'exploded view&quot; that not only makes it easy to identify them, but also can come in handy when trying to figure out how things go together on the tractor.

3. Here are just a few. Korves Oliver at <!-- w --><a class="postlink" href="http://www.korvesoliver.com">www.korvesoliver.com</a><!-- w --> , Steiner Tractor Parts at <!-- w --><a class="postlink" href="http://www.steinertractor.com">www.steinertractor.com</a><!-- w --> and O' Brien County Implement at <!-- w --><a class="postlink" href="http://www.obci.net">www.obci.net</a><!-- w --> .  All three are very reputable and will have many of the parts you need. The last one has many salvage tractors and is good for used parts, as well as new.

4. I'll attach a picture from the parts book. This is about the best I can do right now. There are water temp, oil pressure, and amp gauges, as well as a combination tach/speedometer. 

5. You're right about the paint scheme, it came with green wheels. There are basically two opinions, paint it right or paint however you want. There will be some that tell you that you have it painted wrong if you go with red wheels, but it seems to me that most go that way because they like it better. It's not very often that I see a restored Super 55 with green wheels, even though most of them came that way. I personally would paint it original colors, but it's your tractor, and more important, your money. If you are in need of decals, you can get good ones at <!-- w --><a class="postlink" href="http://www.oliverdecals.com">www.oliverdecals.com</a><!-- w -->

Hope this helps some.
