Welcome to Reef2Reef Eddie! Looks like you've made some solid choices.
You should get a refractometer, and some test kits. You need an alkalinity (KH) test kit, Nitrate (NO3), Phosphate (PO4) in a readable low range, Calcium (Ca), and a Magnesium (Mg) test kit. (I like salifert test kits, for KH, NO3, Mg. I use redsea test kits for (PO4) or a Hanna ULR Phosophorus checker).
All of those things seem like they are unimportant, but they are the only way to tell what's going on in your tank until you learn all the visual cues that it gives you. Plus they will help us, help you when you need it, if you can provide those parameters.
I look forward to seeing you/ your tank grow in this hobby!
Don't be afraid to latch onto one or several of the members here who you like their style of reef keeping. Almost all of us enjoy sharing this hobby with others and are more than willing to answer any question no matter how trivial it may seem at the time!
Happy Reefing
