jd, I think you pretty much have it all covered!!! as for a QT tank all you need is a heater and maybe a powerhead. I also like to put a few fake plants in there. just to give them a little shelter.
And for feeding I would get some mysis shrimp (frozen) and a good quality flake food. to start, you might have to get specific for some animals. but I think the 2 above will be a good start.
for water changes you will need something to siphon old water out of the tank. and then a good clean bucket to mix saltwater in and a powerhead to mix the new saltwater and that is pretty much it buddy.
YOU ARE WELL ON YOUR WAY BUDDY!!!!
