When I brought my Puddy home at age 6 weeks, she was a tough gal. She had a bad leg so she walked like John Wayne and my husband called her Jane Wayne because of her swagger. She thought she'd bully my big girl Pidgelet but Pidge put one paw on her head and held it to the floor until Puddy calmed down. Puddy needed to be put in her place and so does your kitten. They're all going through an adjustment period, so take Karen's advice and get out that squirt bottle and don't be afraid to use it. And if I may be so bold (even though you didn't ask for my advice on this subject), please reconsider not declawing. It can cause your kitten so much pain now and later as an adult cat and that in turn can cause even worse behavior problems.
