Please do not declaw. It is horrible to do that to a cat. When you adopt any animal, you do so knowing there might be issues, such as furniture, litter boxes, vet bills, etc. If you are worried about your furniture getting scratched, don't get a cat. They do not all scratch the furniture. Make sure to get plenty of toys for entertainment, scratching posts, quality litter so there is no odor, clean the litter box at least once a day, change the water daily, feed them good food, if they are long haired they will need help with grooming so they don't get matts in their fur, they need a pet bed, and they like to have a place where they can hide..like an empty box keep their nails trimmed, make sure they don't get into any thread, be extremely careful when using the rotary cutter--some cats love the rolling blade, careful when you are sewing so they don't stick a paw or tail under the needle, provide a space near a window so they can sun bathe, and most of all, love them. Adopt 2 kittens so they have a friend to play and grow up with. They, and you, will adapt much easier. Please do not declaw!!
