One can use any charges.

Getting the charges into the DOCK ligand mol2 input file will
need to be done manually.  Chimera's dock prep does not support
RESP; this link is still apt:

Amber offers tools for helping with the quantum.
I would probably use antechamber after I had the quantum chem
calcs completed:

antechamber -s 2 -i ligand.gout -fi gout -o ligandresp.mol2 -fo mol2 -c resp

The DOCK Amber score preparation scripts do not support non-AM1BCC
charge models.  This feature will exist in 6.3.
