No reason to go with 64bit linux unless you *have* to. 32bit will work
fine and at the same speed, plus for some things (like win32codecs)
actually be easier to setup. I run 32bit on my dedicated backend and
my dedicated frontend.

you can always get a USB wireless adapter if its just for guide data.
Of course if your getting a free card use it for now =D

yea, go ahead and use that, wasn't sure if you had a PVR card or not.
Wireless for non-HD is fine, but for HD, forget about it, just suck it
up and run some CAT5e =)
