Welcome. A few things to know that will help you immensely, as this is your first bike.
There's a book by a member, that is better than any/all manuals produced with excellent documentation and guidance on repairs, maintenance, and improvements for your bike. You can find it here:
http://www.sohc4shop.com/catalog/index.phpAlso, the "screws" on that bike are not Phillips, they're JIS and need a completely different set of tips to remove them without tearing them up. You can find a very good quality set of them, plus an impact wrench here:
http://www.mcssl.com/store/rrr-tool-solutionsUsing these two "purchases" alone will save you more money and time than the benefit of experience of rebuilding a dozen motorcycles. Of course, the support and assistance from many members here is not to be discounted either
. Start a build thread in the "Projects" section, and get documenting on your new adventure!
