Can anyone recommend any tutorials for learning how to read a smith chart and also using the Sim Smith application ?
I want to be able to design coax matching stubs and am a total newbie.
The smith chart is intimidating to me but I thought I would see if I could master it.

Here's a QST article of a very good basic introduction to the Smith Chart that should remove the intimidation very quickly. ARRL membership may be required for access:

Another is the excellent three-part QST series by Ward Silver, N0AX. Part I starts here:

Jim, K9YC has drafted a very informative PowerPoint presentation on Sim Smith:
