I've never used either of those tires but they both seem pretty good for a new track day rider and canyon carver. I wouldn't hesitate to run either if I were you. Sorry I can't be of more help, maybe ped or cali_rider can.
About the fairing, the more you take off, the less you'll have to replace later. It all comes off pretty easily, so if my bike was mint, I'd probably remove it. I've run some fast tracks naked, and you notice the wind on the front straight, but it's no big deal really. You'll see a handful of naked SVs etc. at the track I'm sure.
