Welcome to the forums
Nope - shouldn't matter.
Though models such as the D-LINK DIR-655 will give you the ultimate range and wireless performance.
As for a printer, you could buy a fully wireless one, or one that stays plugged into one of your computers and then can be shared over your network wirelessly with HomeGroup.
Hope this helps
** EDIT **
I didn't see the part about wireless and compact.. Something in the HP line should give you great printing results regardless of size, though it will probably be more expensive..
