Anyway, just go to the main page (
http://www.faforever.com) and download FAF - you can't miss it, there's a huge green download button on the right side of the page. I believe you don't actually need your cd key to play through FAF, and it will automatically patch the game for you when you try to start a match.
As for steam, the community there is small and doesn't have very many good players, so I wouldn't recommend it. The best place to play online is on FAF.
I wouldn't bother with the campaign, it kinda sucks although zep's working on a multiplayer campaign (again, through FAF). You would be better off watching casts, replays and playing a few matches if you feel rusty. Asking a trainer to help you is also an idea, there should be a thread around where you can see who they are.
I really can't answer your CPU question but I'm sure someone else can. You don't need a great CPU though as long as you stay out of things like Setons.
Good luck.
