I think I've forgotten how to fuel properly.

I think the overall umbrella is that I really need to get a metabolic test done to determine exactly how many calories I'm burning. At least armed with that knowledge, I can know for sure how much I should be eating for optimum performance. Anyone have any experience with that?

Neh, I don't know how much that will really help. I've had a power meter that can tell me I'm burning 400 calories an hour, but my stomach only seems to be able to handle 250 an hour -- during longer rides, you'll pretty much end up in a deficit no matter what. That means I need to really pay attention to my hunger cues *after* a ride to restock the muscles, and not just blaze into a burrito and margarita.
