There's a specific forum for full ring hands, you're going to want to post them there in the future.
Pre is pretty marginal.
It's close. If KQ weren't possible for a straight it'd 100% be a cooler. Even so it's still kind of a cooler. Most players are so bad at 2nl that I think you'll see plenty of sets and two pair at a high frequency.
