Dumb question but....

I have a Nokia 3650 and an IBM Thinkpad 600e with Gentoo Linux and a
D-Link DBT-120 dongle. I commonly use T-Mobile USA for GPRS. I've
brolen my trackpoint and I have an optical mouse to replace it. I could
buy a keyboard off ebay but haven't yet as I keep getting new toys. I
would like to try a bluetooth mouse. But obviously I need GPRS to work
on the 3650 at the same time as a connection to the mouse. Would even
be nicer to have a headset and a mouse interfaced with my laptop all
during a GPRS connection on the 3650. Possible?
