parallel wiring batteries
Once I have cabled my batteries in parallel, does it matter which battery I attach other neg and pos cables (such as generator, inverter, etc.) to.

Don,
I've never seen 12V batteries built the way you show in your diagram above.
All 12V batteries I've seen have the positive and negative terminals along the same side of the battery, so that when you line two of them up as in your picture, a negative terminal from one battery winds up being very close (less than 2 inches) to the positive terminal of the other. I don't like this - it kindof seems a bit "dangerous" to me from a possible shorting viewpoint. But one just has to live with it .... or flip the batteries to get two positives next to each other (safer) or get two negatives next to each other (safer). However doing this means playing games with heavy cable loops to make sure that all cable paths are identical for balance.
