There are several automated methods to do what you're asking.  Most of
them are summarized in the following reference:

Cherfils and Janin, Curr Opin Struct Biol, 3, 265 (1993).

As far as minimizing two docked proteins, the following reference
contains an algorithm to do it without disrupting the structures too

Gibson and Scheraga, J Comp Chem, 15, 1403 (1994).

The program described in this reference is available from QCPE
(reference number 659).

Good luck.
