This sounds like a distinction without a difference: if the sugar is not
covalently bonded to the protein, then one prepares amber library files and
pdb files in exactly the same way, whether or not a protein is present.
Make sure there is a TER card in your pdb file between the protein parts and
the sugar parts.

What you have described sounds OK to me. Of course, check things yourself:
e.g. run a minimization of the complex, visualize the resulting structure in
some program like VMD or Chimera, and make sure it looks like what you think
it should.
