The only reason to do this would be to build prepin files
for any residues missing from the standard database. In which
case I expect that the residue would be separated from all
other residues, tho I don't know antechamber procedures.

If you are using Woods' residues, there should be no reason to
build a prepin. Prepin's are made for each new residue type.

No reason to do this - basic procedure is
1. load all residue templates and parameter/frcmod files
2. load pdb with whole complex.
If all residues are defined correctly, all bonds should be drawn.
It may be worthwhile to study the examples.
