Did you search for "xna title screen"? A cursory glance and it shows videos, tutorials, etc on that very topic.

"Error loading "terrain". File contains Microsoft.Xna.Framework.Graphics.Texture2D but trying to load as Microsoft.Xna.Framework.Graphics.Model."

Sounds pretty self explanitory to me. You're trying to load a file into a Model object with data that is not a known model type. It seems to think this file has been compiled into a Texture2D, which sounds about right. If it managed to actually compile it as a Texture2D, then that's probably what it is. Otherwise, I'm guessing it's a junk file. Any way you slice it, it sounds like it's probably not a Model.

If this is not a standard file such as .FBX, .JPG, etc., you need to build a content processor for it by extending the content pipeline.

If it truely is a model, such as a .X or .FBX file, then it's really odd that you would use a model for the terrain.

That would be a pretty advanced technique. I can't even imagine attempting it unless the terrain was for display only. If you need to do collision with the terrain, you're probably going to have to manually pull the model apart and build a height map out of it, so I would think 99 times out of 100 it would be easier to do the opposite and use a heightmap to procedurally generate a terrain. Unity does something similar to this where it will actually allow you to import a terrain model, so I imagine it could be done, but certainly much more advanced then anything I've ever done. And I can't think of a good reason to do a terrain that way really.

If you're not really an expert on terrains, you might want to check out some of the extensive writing I've done on the subject both in my blog and actual working XNA examples on my website.
