Just get 2 of each... I will be down soon and I will bring you more.
As for hermits... get only blue leg hermits... small as possible. As they get bigger they attack snails.
If they try tell you zebras are ok... I would personally avoid them. I find them more aggressive as hermits go and tend to sit on corals regularly.
Avoid bumblebee and sundial snails as coral eaters.
Try find Mexican Trochus (AKA - Red Banded Trochus Snail). Turbos will tend to knock stuff over as they grow. These Trochus are fast and do a great job. Mine even mated in my tank!
here is what they look like
