The list sounds ok except for the and six green chromis.
The chromis are really going to make the tank look over crowded and I don't think they will be that happy.
Just be aware with the pistol shrimp that he digs a lot and make a mess and can make the rocks unstable.
I would also try looking out for interesting gobies and small Nano fish that come into the pet shops.
You get some really cool fish like the yasha shrimp goby, a few other shrimp gobies, pygmy wrasses and hi-fin perchlet
