Of course he is crying, he is a baby and is lonely
and he needs to be occupied while he is awake and he needs to burn energy. The biting while you were on the couch was to get your attention.
Spaying and neutering is a one time shot. Worming is not something that needs to be done regularly unless they hunt or get fleas.
I don't believe cats need annual shots, yes they should have initial ones, but keeping them inside keeps them away from diseases and safe.
Neutering should be done at about 6 months, any later you risk having him mature sexually which could include spraying.
Not sure what you mean by a personal vet, you can usually just call a vet office, let them know you have a kitten and make an appointment.
