I've been trying to chase down a boost or vacuum leak and my trims are out of whack. I can (sometimes) get readings for STFT and LTFT on both bank 1 and bank 2 (STFTB1 and STFTB2). Same with the LTFT. Which ones should I be using?

you dont have a bank 2 unless you have a V8

What confused me is I sometimes still get readings on bank 2. Must be a glitch like some here have misfires show up on cyl 5 thru 8.

yep or just the way they programmed the thing. People with 4 cylinders are just told to ignore it.. Also I need to correct myself. You could also have a v6 and have a bank 2. or even a V10. If you have a W12, you would have like 4 banks lol.
