Grounding Points?? Positive Points??

First off I'm not electrical wizard, my a side from pulling the wires from the harness I haven't a clue as to where they all go...

I'm getting some 2/0 wire to redo my battery cables and was also wondering, What else should I replace?

Grounding Points
Battery to Starter? Solenoid?
Battery to Chassis?
Battery to Engine?
Engine to Chassis?

Positive Points
Battery to Alternator?
Battery to Relay box?

Please help help, I'm sure I've got some wrong or missing some.
ThanX
