As far as chain tension, personally I like to use the B Screw for the final tweaking.
Yup, I thought about graphite powder. I used to have a bunch of moly lubes too -- dry powder and another with a solvent carrier that evaporated. Misplaced 'em a few years ago. Moly works great but leaves more persistent black smudges than graphite.
I might fiddle with the B tension screw, especially if I go to a 13-28 freewheel -- probably necessary to get enough clearance for the big cog.
