By having 2 you have doubled the capacity and available amperage compared to 1. But if you run the system down with the engine off (which is hard to do with 2 yellow tops) You will need a jump. You have no isolated back-up. A good auto-electric shop could put in an isolator for you if you really want one.

In regards to the washers... Do I need any special kind? I just keep putting them on until it tightens down? How tight should I screw it down? Also, is there any danger in messing with the terminal or is it a safe do-it-yourselfer?Just look at how much free space there is on the existing bolt. Then stack the washers a tiny bit thicker, so that it all can tighten firmly.

Thanks again...

Sure.
