I'm afraid I can only answer two of those questions with certainty.
Correct to the first question. With the recent changes a toon cannot use the opposite faction teleporters. They can only use those of their faction.
I want to say that you can still use any teleporters if you change from being factioned to neutral but to be honest I don't have any solid confirmation of that.
A person that declares Kami/Kara is not able to use the opposing neutral teleporters. All those are cancelled out.
I hope this helps for some clarification and sorry again that I don't have a definite answer for your second question.
