OP, for someone at your experience level, you can use a fairly straightforward system for playing Aces.
Preflop: Open the pot in any position for 4-5x the Big Blind. If re-raised, shove all-in. If someone opens in front of you, raise him about 4x his raise. Try to go all-in preflop if you think you will be called! You want to get all your chips in the middle right away, because you DO have the best hand in the world right now.
If, for example, you opened for 4x the BB, and were called by, for example, one person, you now have to do some flop-play. This goes far beyond just your aces! Look around the golden archives and in good poker books
for advice on reading the "texture" of the flop. With AA, your hand will likely NOT improve on the flop, but you probably DO have the best hand. In almost all cases you should bet right out, hoping someone with Top Pair Top Kicker calls you.
There's no shame in taking a small pot with pocket Aces. It is often said that with AA/KK, you will probably either loose a huge pot, or win a small one. So be careful when you have AA and someone is looking to play a huge pot (unless you hit Trips or something).
