If you have the option, sumps are better. Skimmers are a very good idea as well. If money is an issue, dry rock is way cheaper, and you can mix it up, anywhere from 100% dry rock, to 100% live rock. Those lights might be OK for those corals, but you will need to replace the bulbs (and every year at least after that), and try to get the coolest bulb possible (highest Kelvin rating, not funkiest).
dividers (same stuff as sump. I.E. glass or acrylic) to seperate into 2 to 3 sections.
skimmer to fit sump
2 heaters (primary and backup set to 1-2 deg cooler so you notice when primary fails)
tank needs an overflow, either HOB
or drilled tank.
dry rocks for added bacterial filtering (not critical, but it helps)
light (very important as the sump will export nitrates and phosphates)
macro algae and/or plants to work with the light.
