Quick paste to get you started~~
As far as where to start you will need to start with removal of the rusted parts. Then order of new parts will be somthing like this.
1) floor boards (this part has the inner rocker attached)
2) Kick panel
3) "A" piller bottom if needed (they all most always need it)
4) rear half of inner rocker
5) outer rocker
That will be close from what I can see from the pick. Check out this post for simular repairs that I have done.
