I would buy those wheels. The bike may not be "all that" but it is a decent bike if it fits. I rode mine today that is not as nice as yours and had a great time. +1 on Craven Moarhead. if your wheels are steel then definitaly yes.

I ride on steel wheels and have a good time, so if they are sold already then don't worry to much about it.

Stem shifters are ok. not really racy but they tend to work. look around at things that other people have before you get all exited and start your upgrades.

the thing to remember is that it is a bike, not an investment in your portfolio. That bike needs to be made a comfortable tool for moving your body around and doing it well. After you have a stable filled with tange, colombus, 531, and Vitus(yes vitus, I like vitus tubing) you may find yourself grabbing that bike "just because". good luck.
