Don't drive as fast as you can, have some in reserve. In all seriousness, you can go a steady 30mph the entire way and still have an awesome ride. There's other traffic on the road after all. Keep your head about you. My rule of thumb is to not make the tyres squeal, as it means you don't really have anything left. Give yourself plenty of time to slow down for the corner until you get used to how the road flows. There are some pretty nasty switchbacks though. Look ahead, don't get sick. If you feel woozy, pull over. Don't tailgate bikers since they might go down.

KAX already said it, but it bears repeating...

DO NOT CROSS THE DOUBLE YELLOW LINES!

oh, and have a good time while you're up there! I would recommend taking the Dragon->Cherahola loop. There's also the Road to Nowhere, and my personal favorite, many fine gravel roads. There's a good one that sort of runs parallel to the Cherahola. I'm going up there at the end of this month for a weekend visit.
