Is their a mel script that will evenly space uv points between 2 uv points? Like on a uv border I would like to evenly space the uv's.

If I get what you mean, this is already a built-in. In the texture editor you can go to polygons->straighten UV border

in your case the defaults will probably be fine except you'll wanna change Preserve Length ratio to 0
