1. Probably wouldn't hurt to set them up, especially if you don't have a static prefix. The good thing is that interfaces can have multiple IPv6 addresses, so they can use both the public address and the ULA. 2. SLAAC should always be enough. Make sure you don't block the ICMP6 messages it needs though (I've been bitten by that once, firewalld behaves weirdly around this).
