Sounds like you're similar weight to me, and on a similar bike ,what I found made the bike on standard suspension a little more comfortable for the road was to set everything to standard settings, then wind back front and rear compression 3-4 clicks and the rebound 1-2.
Preload / Sag set to give 30mm loaded sag (10 mm unloaded all round)
Ride Height - Factory setting (rod length 265mm IIRC)
Sag & Ride height set your geometry, so it's important that these are correct, otherwise it'll turn like a barge. A ride height tools useful here, and not to expensive if you talk to Harv748.
Damping's a personal preference and would depend on what makes you feel comfortable. What suits me on the road is different to what suits me on the track, and probably different to another rider. But it may help as a start point.
I should also point out that I'm not exactly fast, but I am comfortable
