Hi,
  The warning you're getting is because the AMBER parm reader plugin
doesn't (yet) provide VMD with information on angles/dihedrals/impropers.
If you send me the files you're working with and tell me which version of
AMBER you're using, I can try and have a look at this next week when I
have more time available. In the mean time, you might try using
the AutoPSF GUI for this purpose and see what it can do for you.

Cheers,
  John Stone
