New kittens are rambunctious, but you should be able to get them trained pretty quickly.
For scratching on furniture, make sure that you have an assortment of scratching posts available (some like sisal, some carpet, some cardboard, so it’s good to try a few until you find out what they like). When you see them scratching on the furniture, calmly pick them up, move them to the correct area, and praise them when they do it there.
For climbing on tables, a squirt bottle or can of compressed air works very well. Try to be sneaky – if they know you’re doing it, they stay off when you are around. If they think that water appears miraculously from the skies, then they stay off all of the time.
As for scratching, make sure that you’re not doing anything to stimulate an attack (play behavior with your hands). Play should be with a toy. When they try to play with your hands, distract them with a toy and displace the behavior onto the toy. If they still try to play with your hands, give a sharp, loud “no” (or some other noise – I usually sound like a game show buzzer). Be consistent.
Good luck. Have fun. There’s nothing more fun than kittens in the house. (And then they grow up to be cats.)
