Hi, I'm new here as well, and an electronics newbie with a little microcontroller background (Atmel AVR) trying to dabble in power electronics. I don't know how helpful this is, but I'll respond since no one else has. I've got a project that's similar to yours, in that it will require a buck/boost converter. I've found this document helpful as an introduction:
The Cuk converter circuit seems especially interesting; like the standard buck/boost circuit it boosts at duty cycle > 0.5, and bucks at < 0.5. But, it has low ripple inherently, which might be better for your battery (?)
