Duuuuude... I think you need to make one thread for all your questions. Because a lot of these are totally not worthy of their own.
In this case, just like your last post, you need to be more specific. Licenses describe what a user can and can't do with your software... so what you need changes depending on what your intent is. Are you trying to sell a game? Are you releasing a game open source?
In any case, n00b questions are fine, but you can't just come in and be like "Can someone tell me how indie games work, kthx" and expect any kind of serious reply. You gotta do a little thinking / legwork yourself first.
And work on your spelling.
