For sure get a scratching post! Rub some yummy cat nip on it. Whe the kitty tries to scratch your nice furniture, put fresh catnip on the post and slowly have the kitty scratch that! I made a post from an old pair of jeans and an old log. Doesnt have to be fancy, but be consistant!
I dont believe in declawing either, and it can change their personality too. Plus, if it ever should escape, it wouldnt be able to defend itself at all!
Good luck, I cant wait to hear when you get one!
