For example. I've got the positive terminal in the engine area as well. Is there a specific order the new battery and leads should be connected in? Is the voltage I'm getting normal (11.8v then 13.6v at running)?
I normally hook the positive up first when installing and disconnect the negative first when removing the cables.

It actually doesn't matter which you do first no matter what anyone tells you as far as the car and battery are concerned.

The reason to connect the positive first is in case you touch the body of the car while tightening the positive cable to the battery with a wrench. If the wrench touches with body with the negative not connected then nothing happens. If you connect the negative first and then touch the body while connected the positive cable you can cause a very bad and potentially explosive short.

The same goes for disconnecting the battery. You disconnect the negative first since touching the body of the car while removing the negative cable is harmless and once its removed if you touch the body while removing the positive at that point nothing happens.
