Long Time Aquarist, First time Reef: Questions

Going to be moving into a dorm in the coming months so I decided to build a reef tank to take with me.

So far I've gotten my tank and lighting.

Tank is a 4.5g rimless, curved corner tank. (35cm x 21 cm x 23 cm)
Light is a 16w (16x 1w blue and white) LED fixture I got at an LFS. The color on this lamp is pretty good. It's a lot more purplish white than the pictures make it out to be.

I'm thinking I might start out with a few zoas and other softies and generally easy polyps and maybe put in an sps or two.

I have a few questions:
1. What size HOB should I get for this thing? Is an AC20 too large? *lookin for something really really quiet too since it'll be a shared dorm)
2. How much water movement should I need? I have a 140gph power head is that enough?
3. What other supplies do I need other than:
HOB
Heater -X
Thermometer -X
Water Movers -X
Light - X
Aragonite
Refractometer
Test kits
4. What test kits do I need for a nano reef? I have the standard ph, nitrate, ammonia, nitrite get up and I also have GH, phosphate and KH. What am I missing if I'm looking into coral?
Fauna will be restricted to typical CUC and maybe some sexy shrimp.

 

lol, this crazy kid on here is doing the same exact thing, but, even though he's a little nuts, he's crazy good and knowledgable about reefing and researched this exact thing to the cow's come home. Check out his thread, but don't tell him I gave him prop's! lol

I'd say this sounds like a great Nano! But Seano is practically an experience when it comes to coral. Welcome to 3reef!

To answer a question,
100+ ghp is plenty for such a small tank, unless you get into sps then you'd have to ask someone else xD
