help with suspension setup

I have a 99 xcr700 and this is my first sled. I need to know how to setup my suspension for northeast trail riding. I ride somewhat hard and I am confused. When I was riding last weekend, the front was bottoming out on the bumps while I felt like I was getting my a** kicked in the rear. Where do I start adjusting?? I am 6'2" tall and I weigh about 205. Any help would be great.
