Im not an expert here but Im pretty sure the 21 splin is not compatable with your tranny unless you already have a 21 spline tc.

No, you do not. It is a good upgrade though to go to the newer style CV joint, especially if you are going to lift it.

You do need to make sure you have a 21 spline input shaft. That wasn't mentioned, so I did not bring it up. I have done this swap. I am not sure when they went back to 23 spline, but a 231 out of 87 - 90 will work I think.
