The conversion form metric to English is based on 1" = 25.4mm. 4.25" is 107.95 mm. You should be able to measure the fork yourself, but yes, the first machined groove is at 5mm.

If you have any complaints regarding understeer (front end push) on corner entry, try less sag, like about 98mm.

Yeppers. Set (or in your case, reset) sag and THEN make changes to the forks. And properly torque those fork bolts; too tight, especially the lower ones.
