V, 1st of all be sure to take and pass the MSF course first. Best of luck with it, it's a great experience.
The Speedmaster is also my first bike and I got it about 3 weeks after passing the MSF course. It has been a wonderful bike from the start. It's so accomodating of a new rider and a blast to ride.
With all due respect you DO NOT have to ride it home from the dealer.
Due to inclement weather my dealer was good enough to deliver the bike to my driveway and I'm darn glad they did.
At first I was able to get some much-needed practice around my neighborhood, then around town. I moved up to the interstate after not too long and now ride 2-up with the wife.
I have a grand total of about 3,200 miles on the odometer and it feels like I've been riding the Speedmaster my whole life. But I don't take it for granted either.
Every mile is a learning experience. Just take it slow and learn at your speed. RIDE YOUR RIDE.
All the best!
