How do I configure my network.

I have ATT DSL:: 2701 HGV —and I am trying to connect a Cisco e3000 wireles router for my 1st floor and a Cisco e2000 router for coverage on my 2nd floor. I cannot get the IP adresses correct. I also have a netgear GS108t smart switch in the mix which I am currently avoiding.I need some configuration assistance.
