Getting it live is definitely the most important thing! Then you can download demos for quite a few retail games and trials for EVERY game on live arcade.
Apart from that Dead Rising is a must have imho. Kameo and Perfect Dark are worth getting and Condemned is also worth checking out you did not play it on PC.
All the multiplatform stuff you probably know about already...
And since I am using my Gamertag on Windows you should be able to use yours on you Xbox!
