I don't want to sound harsh but the thought occurred to myself; shouldn't you ask those questions *before* buying? :P
Word of advice: take the time to read as much as you can on these forum, you'll end up knowing what to buy and what not to, what's worth how much, and so on.
As the guys above said, you got an OK deal I think. Nothing to worry about, nothing to consider yourself the luckiest guy in the world :P
