Battery Problems please help!!!!

Since you've replaced the battery and starter, I'd also start looking at other issues with the electrical system. It could be ungrounded, causing a slow dissipation trickle. You could also have a defective accessory or light fixture, basically anything that would be putting a constant drain on the electrical system.

I'm a sucker for punishment, so I'd just start tracing every lead and make sure it's properly connected and where applicable, grounded. I'd also disconnect any A/C or heater system, radio, etc, to see if that cures the drain.
