3) are label changes in gmail synched into the local emails?

It pulls labels from gmail messages into notmuch, with the labels in tact, once per each email.

Okay, it's way more robust now. Just updated it. Now it will pull gmail labels to notmuch, each time, every time. So you can run this thing over and over, and it will always push gmail into notmuch. It doesn't yet sync the the other way yet, but at least this is now fairly robust.
