NEVER WIPE THE FILM WITH ANYTHING!!!!!! Yes, I yelled that statement, for good reason, to avoid chance of scratches. Final rinse of Photo-flo in distilled water, drain the reel, then shake the excess off while the film is still in the reel. Hang your film vertically in a dust free environment(shower stall) and leave it alone for a few hours to allow the emulsion to harden properly before printing or scanning.
I always presoak for a minimum of three minutes then develope. If all your chems and tempering water are the same temp you shouldn't worry about temp swings. The amount of change is negligable. The trick is to learn to be consistant with your routine.
