It's a great bike and you should have a terrific time on it.
I like the recommendation of using the kill button to cut off the bike - it makes it a reflexive action in an emergency. (It also familiarizes you with the kill switch and prevents the "Ohmigawd! The bike won't start!" drill that so many of us have been through at some point in our riding career.) However, none of the methods will hurt the bike.
A lot of us have done our own seat mods. I did mine in about 30 minutes and it cost me all of maybe $15. Looks fine and rides great. I often ride 500 miles a day and since the mod, that's not a problem. I also wear cycling shorts beneath my armor - that helps a lot too. Seamed boxers suck!
If you decide to go with the mod yourself, something I recommend, there are several threads from those of us that have done it on the forum.
The Air Hawk cushion on this Vee at our Tellico gathering provides an inexpensive, very comfortable ride. Some riders have even put them beneath the upholstery on their bikes.
Here's a Corbin from the same meet - it looks really good but I haven't had the chance to try one out myself.
Here's my mod - I used a few layers of Ensolite sleeping bag pad layered over with memory foam. It feels like I'm riding on air and doesn't slope forward at all.
Talk to the guys for a while and then go for one of the options - IMHO, the seat is probably the biggest weakness that the stock Vee has.
(For reference sake, I'm 6'5" and I weigh 220 lbs. Some lighter riders have reported that the seat is fine for them.)
