For paint chips, based on the research I did, I purchased a "paint pen" from AutoVisuals.com I have not used it yet but it looks like a better solution that the typical touch-up paint.
As far as cleaning, waxing, etc. goes, you said you'd been to DetailersDomain.com Phil has a lot of stuff there and good prices; I can understand that you might find it difficult to know where to start. As mentioned, Phil might be able to recommend a couple of starter products.
Another option, because you're in the area, is to attend one of Phil's "detailing days" and get your car detailed. He might have one coming up this month; check his forum.
