Hey Roozer,
Base Offense is a fairly even offense, not weighted either heavily outside or heavily inside. I would suggest that you are on the right track with D, you could certainly also follow his lead with Man to Man or if your centre has really good ID and your PF has some sort of OD you could also give 1-3-1 a roll...
I won't say much on your O because I have a better feel for the guard focused offenses but maybe if you PF/C have good IS which it seems for your post they carry most the weight, you could play low post.. Good luck with what ever you choose.
