Blender UV Mapping

I'm not entirely sure I'm posting this in the right place, but it relates more to texturing than anything.

What I'm trying to do is bake textures in Blender for use in SL. Right now I'm doing simple tests with spheres, cubes, cylinders, etc. I've got the baking process down, but I'm having issues with getting the textures into SL. I can't figure out how to get the UV mapping right in Blender so it matches SLs UV maps. The closest I seem to have come is using top view, switching to UV face select mode and hitting U then choosing the shape I'm trying to work with.

Please help! Thanks.
