I also second on the K.I.S.S method... I've got a complete re-wire project coming up on mine. I've got a few plans to run a dual battery system with a Automatic Charging Relay installed between the start battery and the house. Blue Sea Systems makes a really nice kit.

My thought on running a dual bilge pump system. Make sure that you run two separate switches/powersource for those. Just in case one pump goes, blows the fuse, etc... that way you have a way of running the back up one. There is nothing like trying to troubleshoot a blown fuse in an emergency.
