You might want to check the headset too. Pull the front brake with the bike on the ground, and rock the bike back and forth, if there is noticeable movement from the front wheel then your headset needs to be tightened.
As for the back wheel you can't take it to your LBS and they'll true it, and it shouldn't be more than ten bucks. I think it's worth it to see if that works then fork out the dough and buy a new wheel.
I think that's Dura-Ace AX. Here's some pics of the AX gruppo.
