New to Game

I new to the game and looking forward to getting sucked in.
I was wondering if someone could point me in the direct or offer up some advice setting up things like salary cap, contract limits, etc. for a realistic feel for playing out an NFL season. I have a few holes in my knowledge on these things, so I appreciate the assistance.
Thanks,
