I have an obj that has UV's already assigned to it and just want to relax those existing UV islands a bit...is there a way to do that?
Everytime I open the obj it start my uv process from scratch and I can't get into the existing uv islands that are currently assigned to that obj.

Ahhh, just as I posted this I figured it out...Edit UV.
But that is leading me to another question...

1. If I can select the UV islands through the materials can I isolate that island so that it is all alone?
2. Can I select and freeze the boundries of that island and just relax the insides?

" can I isolate that island so that it is all alone?"

I'm not 100% sure what you mean there, but when you select a material from the list, it green marks those polys, so you can do anything then that you can with any other green marked polys. If you want to detach them, use Enter over those marked polys. If you want to hide everything except those shells, use the hotkey sequence H-G to hide them first, the H-S to swap whats visible and whats hidden.

"2. Can I select and freeze the boundries of that island and just relax the insides?"

Yes, use Shift-P on one of the boundary points to pin the whole boundary, then you can use "F" to flatten that shell and the boundary will stay fixed. If the internal UVs dont flatten out nicely (because of the pinned boundary) try scaling the shell up and flatten again.

The material group selecting was added in v2.06.02, but the boundary pinning has been there from almost the beginning.

If you ever want to know whats new for each version, scan the Updates forum for anything with "UVLayout vX.XX now available" in the title ...
