Do I just make a P+ connection on a PWELL unit cell and the connect this cell liberally on my layout ground plane ? Any other suggestions, issues or tips ? Thank you.

If your circuit has BJT which has more than one VSS connections, for example normal VSS and VSSPS connected to collector. Then pay attention that the substrate is needed to connect with VSSPS instead of VSS.
