Have this problem modeling

[Mark]

Can someone explain what to do after this point?

Helping you to do what?
Creating a texture or exporting to glest?

If the problem is the export:
Your model only has quads no triangles yet. The export would be empty.
Go to edit mode and call mesh->faces->quads to triangles.

export is done in object mode then.

I need simple instructions for getting the texture to stay on the model.  Before it would show up as blank white when I opened the G3D.

So in the picture so far i have marked seams and have gotten the texture to show up on the image editor.

In the left window ( where the uv-layout is shown ) say UV's->Scripts->Save UV Fave Layout.

Than you get a background tga which you can use as a layer in a painting program (gimp).
see also here, this video helped me a lot learning it:

the "LSCM UV Mapping" video:

Just for your info the uv mode is now included in the edit mode and the video was made with an older blender version.
