I would say for sure get the vaccines. He is not yet neutered and will be desperate to get out soon if not already. You want to make sure he is neutered soon. Declawing cats is extremely painful for them and leads nipping and arthritis. It is also unnatural and unnecessary.
As for the diarrhea some have suggested probiotics. I really haven't had to deal with that. I know you are trying to work with your vet to solv this issue as well.
Tell your husband he is responsible to help you both physically and financially. He did purchase the cat as a gift, which is not a great idea usually. it also seems he may have went to an irresponsible breeder if you two haven't been in contact at all since his purchase.
I believe that you care for Casper so please don't have him declawed. He is kitten and getting him neutered will settle him down some but its partly age
