If you split connected end nodes between the two routers, you will have major issues if devices need to communicate with each other because you would have 2 separate and firewalled network subnets. Music sharing, file sharing, printing to a network printer, etc. will all be adversely affected. If you do opt to daisy-chain routers, the only thing that should be plugged into the 2Wires LAN ports is the other router. Spring for a $20 4-port switch if you must... you can even get a 8-port switch for under $50.
