Well wireless = always more lag then using a normal UTP (network) cable.
Especially if you're gonna play shooters... -DON'T- go wireless... lagggg....
Just get a (custom length) network cable, and measure the number of meters you need first carefully (and add some extra meters of course). After that, just spend your time carefully hiding the cable that runs through the whole house, really it's much better then going for wireless...
Oh and about your xbox360... don't get the one without a harddrive, you'll miss out on a lot of xbox live content (free video's & demo's), other then that... just go for the cheapest xbox360+harddisk combo.
