Grounding questions

I am getting ready to rewire my entire car. I want to know what everyone is using for grounding there cars. I currently have my battery mounted in the trunk. i have 1/0 cable going from the battery negative terminal straight thru the floor and grounded to the rear frame rail. On the engine, driverside front cylinder head i have a 1/0 flat braided strap going to the driver inner fender where the factory battery would have grounded. what else do i need guys?
