Help!

We have a project with two subcontractors that will be funded shortly as a
grant from ONR.  One of the two subcontractors is a commercial firm.  We have
very little experience in subcontracting to commercial firms.  Can anyone help
direct me to the appropriate regs?  The ONR terms and conditions indicate FAR
Subpart 31.2 applies to commercial firms.  What about A-110, A-21?

Any guidance you can send my way will be greatly appreciated!
