I am moving the contents of a 10 gallon tank to a 18 gallon tall tank (same footprint). I have Fluorite substrate in there that I am going to transplant. Since I am already disturbing it, should I add any fertilizer or supplements to it?

I wouldn't bother. The only fertilizer that the fluorite should need is found in fish waste, so you should be good. The fluorite provides the big mineral, iron, pretty much forever.
