$250 for a spay isn't bad. I almost paid $350 for my doe (I'm only 18, and I've paid all my vet bills since I got my bunnies when I was 15) so I know howit is tohave to pay that muchbut you can't put a price on a good vet. And considering you live in NY, that honestly doesn't sound that bad. If you go to that link like I said, you can see where Long Island is in relation to you.
Vets will trim nails for a small fee but as for grooming, that is up to you. There is no such thing as a bunny parlor that I am aware of, but constant shedding can be caused and most often is caused by a poor diet. My rabbits used to shed constantly and I've seen made diet changes and one of them has stopped shedding almost completely except for the one moult he had before winter.
