Yup; works fine.

Yes. BGP and however you derive your "IGP label(s)" are completely
independent.
Up until fairly recently, you needed to configure TDP or LDP on the TE
tunnel to bring up a [TL]DP session with the tunnel tail. Why?
Because we were treating the TE tunnel like any other outgoing
interface, and needed to learn an implicit null label for the tunnel
tail, via the tunnel. This was fixed somewhere around 16ST; I don't
have the bug ID offhand, but can dig it up if you're interested.
But once you do that, everything works fine.
