ten degrees base isn't much advance. Typically, I'd say pull 2-4 degrees to be safe on a 100 shot. Having the timing at factory spec may mean you will be ok to leave it there. I believe I ran 14 degrees base on my old fox and dropped it to 8 or 10 degrees for a 150 shot. It has been so long, I can barely remember the little details. Sorry I'm not much help.
Yes, get a colder plug. One step colder should be fine.
