They should get shots, Better Safe Than Sorry.

Yes
No. Unless the animal has reproductive deformities or cancer, it is actually dangerous to perform the surgery. There is no need to have them spayed or neutered if you are being a responsible owner.
Yep you are totally fine
Phone your vet and they will tell you. Let them know how old your kitten is. As far as full grown cats they require a 'cocktail' shot and also rabies shots. It's important that you keep your pets shots up to date to keep them healthy and well.
Anyone who has or is, developing an allergy, may need to get allergy shots. There are many ways one can develop an allergy: to outside or inside pollutants, allergic to dogs or cats, allergic to metals, etc. Usually one gets allergy shots when the allergic reaction is so bad and persistant, that they need to seek professional help.
Cats should see the vet as often as the vet recommends the cats be seen, but I think usually once a year. My barn cats saw the vet when they were fixed and got their first shots about 5 or 6 years ago. They have not been back since, but they are barn cats.
Bunnies don't need shots
they need all of the same shots as othe dogs.
Rabies* shots are around 50$ themselves. Plan on a 100$ examination fee as well. Total: 150$
Yes so they can get their shots and have a check up like you and me!
No rabbit normally needs shots. However, if you are showing your rabbit it could possibly need shots to be shown.
