when I make a UV map and there are little red dots on the vertices what does that mean?

Uvmapping is all about points, and alittle bit about polygons if you have support for discontinuous uvmapping. When you uvmap a polygon, it's points are assigned uv coordinates. But usually the same point is be shared by many polygons. You might want to uvmap those other polygons in a completely different place in the uv map, and not next to and connected to the previously uvmapped polygon. So for each of these polygons you need to assign a different uv coordinate for the same point. It's each of these instances of the same point which are displayed in red!

Mind you LWs discontinuous uvmapping (which is what you call this) is rather poor in terms of native tool support and workflow, but it does work.
