I would use balsaright to seal the wood, you may be able to use thinned epoxy. You don't need a fuel dot. It should come with an on / off switch, most of them do. A peak charger would be nice, couple of gallons of fuel, spare battery for the glow starter, a solid restraint system - I use a tent stake that looks like a nail, with some good cord in a loop - that will keep it in place for you when you start it. You will fly the dickens out of this thing. I have 2 that I use. Good luck!
