It looked like the math could end up with a 97" stud on the high wall which would have to come from a 10 ft board , that's all. Yes I think you math is fine.

Well, I already have 8 feet 2x4s so I would use them so it would be 96" instead 97" which is ok if its one inch lower...its fine...I have to adjust one and half inch for double top plate any way......I have to cut only the lower walls from 8 feet boards...
Thanks for all your help...I don't think I have any more questions as of now..

You should cut all the stud with angle on top, same angle as the pitch of the roof.
Square to long on the high wall and square to short on the low wall. Keep the top plate short on both walls so the side wall top plates overlap and tie everything together.

Ok thanks a lot..

Ok one more question...the lower wall should also have two top plates and one bottom plate ..total 3 plates?

Yes the top plate is held back so the top plate of the side walls can overlap. That locks the corners together.
I just went looking for a picture to show what I was talking about. I guess I've been over building sheds. No wonder most look so crappy after a few years.
I did find this write up.
