EDIT:

I found these:

I think I will use these, if you all tell me they are solderless and the sleeves crimp onto the wires to hold them in.

To set up two external terminals I would need:

0.250'' Vinyl Insulated Piggy-Back Push-On Would need two, one for battery positive and one for negative.
0.250'' Vinyl Insulated Female Push-On Would need two, one for top of piggy-back positive and one for piggy-back negative.
16-14 ga. Vinyl Insulated Ring Terminal Would need one each for around each screw (one for starter and one for charger).

Would also need two #6 screws, four #6 hex nuts, two #6 lock-nuts, two each of red and black wires.

The two 14-gauge black wires and two 14-gauge red wires would be crimped onto the piggy-back terminals. Then the wires would go up and be connected to the ring terminal
Please tell me that they are what you suggested in your previous post carrelh and that they are solderless and the vinyl sleeves crimp, and they are the correct size I will need (the blue-colored terminals which are 16-14 gauge).

If this would work then my problems are solved and I can get to work setting up my terminals.

I still would like to know if I can get zapped on the screw?

I would like to have two terminals, you never know when you would need both. And they will be far enough away so as not to short each other out.
