Congrats on the new bike. Sorry but I can't help you on the seat, I'm still running my stock Corbin.
As fas as "other important things I should be aware of" , I would say just keep a close eye on all your bolts and nuts, they will back off from time to time just like a V-Twin. I think the factory has worked out a lot of the problems that the older bikes had so you should be pretty much good to go.
Remember not to pick your nose or anything like that while your on the Boss because you can bet that someone is looking at you.

If you don't like talking with folks or your in a hurry don't take the Boss. Allow for extra travel time when stopping at a gas station or a store.
Other than that I'm sure you'll come to love the bike as much as this fine group of folks have. Make sure to tell us all about it when you get it and post some pictures if you can.
Take care
