I know the book "Game Art for Teens" (stupid title) talks a lot about creating levels in Maya. As for stuff online, um, I've never bothered to look.
As for getting the actual level into Blitz, you can export obj and open that in gile[s], or you can export DirectX file format and convert using Ultimate Unwrap. I'm working on a b3d exporter for Maya, but am already WAY behind in finishing it.
