To re-quote what I posted over there:
Raw veganism is a subset of regular veganism. Regular vegans do not eat anything that came from an animal. That includes all meat, fish, eggs, dairy, and usually even honey. Raw vegans only eat foods that have been uncooked, or cooked to less than 115 degrees. This means mostly fruits and veggies, with some nuts and seeds thrown in.
Personally I think the most important thing is to look at why you are changing your lifestyle. If you are doing it for purely health reasons, then my best advice is to eat as many whole foods as possible, raw or not. Also make sure you get a lot of sun for Vitamin D intake, as well as a B-12 supplement. Drinking or eating a fortified food like soy milk can also help you get everything you need.
Many raw foodists (and some vegans too!) are quite fanatical about their lifestyle, saying things like, "raw food is the only way to be healthy," or, "you will only have success on a high-carb raw diet." Please be wary of someone who says that THEIR way is the ONLY way. Many diets are quite healthy if done right, and it is just as important to pick a lifestyle that you enjoy and can stick with. So, ask any questions you have, do your own research on the subject, and try to only listen to people who have hard research to back up their claims.
If you are interested in the nutrition and health aspects of veganism and raw food diets, I recommend Becoming Raw. It is well-researched and does not make any claims that it cannot back up with scientific studies. The Amazon link is: http://www.amazon.com/Becoming-Raw-Essential-Guide-Vegan/dp/1570672385
