First of all, Welcome to the forum James.
Secondly, I understand where you are right now. Passive solar is a wonderful thing, but there are a lot of different ways to go about doing it. There is nothing wrong with using that south-facing slope and the sun to heat your home. Where many people get trapped is designing a house which defies the geometry of the hill it's built into and have to deal with water issues and ventilation issues.
Personally I am a big fan of the Mike Oehler earth integrated designs as they use mostly indigenous materials and leave your living space as natural and rustic as possible. Plus, I'm not a big fan of pounding soil into old tires with a sledgehammer (as in earthship).
Oehler's design uses the slope of the land in such a way that you take the pressure from the uphill side of the home and let light in that way, while still retaining the benefits of underground. You will find a lot of cool ideas in here. Be sure to read Paul's WOFATI article, as that has a lot of interesting ideas integrated into one and kind of lets you view some of the options side-by-side.
