Congrats on the purchase, I don't think you will be dissapointed.
I would just buy 4 AA rechargeable batteries and charge kit instead of the Play and Charge kits. They aren't very expensive and if you only use 1 controller at a time, you will never need batteries. As for your wireless adapter, there are other ways to connect a 360 to wireless net. I think it is called a wireless bridge, look it up on google.
*****EDIT*****
I forgot to give list a few games for you to try.
Dead Rising
Left 4 Dead
Gears 1/2
Fable2
and the JRPG's everyone else mentioned.
