Aaron,
Probably the last thing you need at this point is another alternative but . . .
I was at the same point as you a few months ago (kind of like drinking from a fire hose, isn't it). I went through several of Mighty's ROMs and a couple from NRG using them with CHT & AHT while trying several of the same things that you are starting to do. I tried a MaxSense ROM from Bignadad (

and found it very much to my linking. Since many of these options (multiple clocks, etc.) are built in and selectable and the MaxSense structure takes care of many of the options in CHT, you get it all in one package. Big's ROM is a bit newer given that MaxSense is new so it is evolving but you might find it to be much to your liking (reading between the lines a bit) based on my experience. Just thought I might pose this alternative to you at this point. Big configures his ROMs for each carrier so it is pre-provisioned (for VZW in your case).
BTW, NRG does have a couple of MaxSense ROMs as well but my experience has been with Bignadad. Good luck and have fun.
