setup wireless bridge

Hi,

I've got 2 wireless routers (usr808054 and usr809108a).
Now I'm trying to setup a wireless bridge with these 2 routers.What are
the steps I've got to do on each of the routers? Is this possible or
not (e.g. one of the routers usr808054 is maybe too old)
Which one of the routers is the best to be the main router.
