Hi Josh. Regarding the fish, personally I would scratch most of them (sorry, just my honest opinion).
AGAINST:
The purple tang's are usually aggressive, well mostly towards other tangs. So that's more of a call depending on what else you plan to stock. I tend to stick with non aggressive fish. Your tank is also on the small side (IMO).
The trigger is going to get way too big and they tend to go nuts at feeding time which may put off other shy fish and frag your sps :0
I'm not really up on leopard wrasses, my impression is that they can be tricky.
Jawfish is pretty but bad track record.
Copperband has terrible track record. I've never met anyone who kept one for more than a year. I have tried and failed too many times. Even the ones that eat don't make it. Look into Chelmon marginalis as a more hardy alternate.
Bartlett Anthias are known to turn male and kill eachother.
FOR:
The Vrolik's is a nice fish. I recently added one. Very pretty, eats pests, peaceful, and will even co-exist with other wrasses including conspecifics. IMO halichoeres are close to ideal reef fish.
Midas blennies are nice fish. I prefer the smaller less aggressive blennies but that's a personal thing.
Bicolor anthias is a nice medium sized anthias. They aren't inexpensive and I might be tempted to spend a little more on the (smaller) P. pulcherrimus, P. randalli, or P. parviostris. Carberryi are an inexpensive alternative for a small anthias. The group size really depends on your total bioload and how you deal with it. I would rather have 5x smaller fish but the science behind that idea may be faulty... all anthias eat a lot. Anyway I would shoot for a group of 5 if you want a shoal and don't want to "use up" too much bio capacity.
Fish are fun, choose wisely
