When I was in high school, my family and I adopted a pregnant street cat. Well, out of the mother came 4 beautiful kitties! Each person in my family got to have their own little kittie and mine is the only male of the litter. 
My cat's name is Kayster. He has been neutered, but not declawed, much like the cat to which you are referring. He is the sweetest and most personable cat of the litter, albeit he is a little dumb. He thinks he is a lap cat and demands attention all the time. 
The most important thing to remember about a cat's nails is to keep them trimmed. I try to set aside a day on the weekend to trim my cats nails, so they do not get too long. If they get too long, that's when the damage really starts to occur. 
Also, if this does all work out and you decide to keep him, buy a Littermaid. It works wonders and you'll never have to scoop the litter. 
Hope this is helpful!
