1. Haven't decided how much if any of the spray rail will be graphite so if I coat the whole rail with graphite will S3 yacht primer be opaque enough to hide the graphite if I decide I want the rails painted?

Probably OK if you are prepared to add enough coats. If I was unsure, I would tend to go the other way - don't graphite the area and add it later if I changed my mind.

2. Will the graphite bond well after sanding with 80 grit paper or should I use a coarser paper ?

Absolutely, it's epoxy! Remember that the graphite is really epoxy with graphite powder added. It's still mostly epoxy and bonds well with darn near everything. Depending on your epoxy brand and speed of hardener, you may need to be aware of amine blush. Sanding can compound it by grinding the blush into the surface being prepped. To be sure, I always got in the habit of washing before sanding with a solution of clear water with a splash of vinegar in it.

Looking good

I want to put a strip of graphite down the middle of my V10 and I've been trying to figure out the sequence for that. It looks like I'll put on primer, then graphite the middle, then mask it off and paint the topcoat.
When I put it on my D15, I just rolled it right over the fairing compound. If it sticks to itself, it will stick to about anything else.

You'll get a better finish sanding using your fairing boards and it will keep you from having any high or low spots that you might have from using the RO. Just use a light pressure on them and you'll be fine. If you don't have paper for them than still go the hand route with as large a block as you can. This is going to determine your final finish. Do a light spray with a quick drying spray paint(black or red work best) when you sand this will show you any high or low spots real fast and you can then add QF where needed or sand down any high spots. Then reapply a primer coat.
