|"and if they both support bridging, and lets say there is a checkbox to enable it in the cpanel's, would i enable it on both wireless routers?"|
No, just on the one that is across the house. The one you want to use as a "wireless card."
This is the exact same setup as my home network. I installed DD-WRT firmware on both of mine because the Linksys WRT54G and GS don't natively support client-bridging. I enabled client-bridge mode on the one that would act as my "wireless card." Works perfectly, and only took 15 minutes to install and set both of them up.
