I just setup a similar thing. I ran 2 lines from 2 different bedrooms (office and kids bedroom) to my basement(unfinshed part, aka laundry room), and mounted the boxes on studs. I have keystone jacks at all four ends. Then, I ran a line from the finished part of the basement (carpets, drywall, etc) into the laundry room, next to the other jacks. Both ends have keystone jacks. I ran a cable line (for the cable modem) into the laundry room, next to the other jacks. Then, I have an SMC 7004VBR router ($10 after MIR at compusa a few weeks ago). All three jacks have wires coming from them into the router. It works great this way. The faceplates, wire, and jacks are all available at Radio Shack (I think i paid like $30 for a 100ft spool). Lowes or Home Depot sell the boxes, but make sure you get the ones for "existing construction". It was a bit scary cutting a big hole into my new house (its only 6 months old), but it looks MUCH better than in my old house (were i had the wires running right through the wall).
