My suggestion is take it slow, don't be in a rush to make a list. I would say take a couple months and research your fish heavily. Mistakes a lot of us have made/make is rushing.
Couple things to think about
1) Is this going to be fish only or do you plan on having corals
2) What type of bottom? Sand, crushed coral, nothing?
3) predator tank
I always enjoy looking at Live Aquaria to see what fish are out there, basic guides to tank size, temperament, reef compatibility etc etc..
One thing I have learned is you can walk away from the fish or coral, you don't have to have it

There are a ton of fish and corals out there so give yourself sometime.
PS Hope you have a couple QT tanks. You going to need them for all the fish you can have
