Relax
It's hard when you're new to riding... There's a lot to remember and a lot to watch out for.
On my sport touring bike, over the last three years, I was averaging 10k - 12k per year riding here in Montana (30k over the last three riding seasons). For me, the riding season is a little longer than most (in Montana) because I don't mind the cold. So I basically ride from when the snow clears up on the roads (March or April) to when it starts snowing again (November - December). The first year I rode up here, I was getting terrible pain and numbness in my throttle hand, and almost none in my left hand. This was more perplexing because I have carpal tunnel in my left hand. I found that I was gripping the throttle way to tightly, without ever really even thinking about it. I noticed that I had a death grip on the throttle most of the time. I had to continually remind myself that I didn't need to grip like that, and loosen my grip. Eventually I finally got myself gripping correctly. After I learned to do that, I bought a cramp buster for the longer trips. Even with carpal tunnel in both wrists/hands, I have pretty close to zero pain and/or numbness now. My last long trip of the year last season was 2100 miles over a three day weekend, and only my legs were sore (bum knee).
I agree with what was previously mentioned, hold the grip like you would an egg. Get used to your machine, don't make any changes until you get to know the bike. Rushing into a cramp buster or throttle boss can have some serious consequences, I learned that the "hard way" as someone else mentioned. Lets just say I now tuck my jacket sleeves into my gloves.
Congrats on the getting the bike, and taking the course. Safe riding...
