I've got to say that I totally agree with Mad Dog Jim. You say you are new to bikes altogether, right? Don't rush out and spend tons of money on things you've "heard" you need. Call the dealer immediately and see if you can cancel the V&H purchase - tell them you need more time to think.
Then I'd follow this process:
1. Take your new bike home, break it in as recommended in our Self Help Tips, and just get to know it and enjoy it
2. Money should first be spent on safety and comfort gear. Helmet, boots, glasses, gloves, jacket, etc. Then comfort stuff like a backrest, highway pegs, grips.
3. Get a Service Manual and any tools you need and do your own 1000 Mile Service
4. Get some good quality fluids in your bike - again, spend some time in our Self Help Tips
5. After spending your money on items 2 through 4 above, now you should have enough miles on your bike to know what kind of accessorizing you want to do as far as chrome, pipes, air cleaner, fuel management, etc.
I know my way sounds kind of boring but it will keep you happy and save you money in the long run versus throwing money at everything your pals and the dealer say you've just got to have!
