For lighting, go with a 4x24 T5 HO
setup, the Sundial from Current USA would work perfectly, even has lunar lights. For powerheads, either two Koralia Nanos or two Koralia 1's. I have the same tank with Koralia 1's and get plenty of flow. You don't need a skimmer as a weekly pwc
will accomplish the same thing. For salt, I would just start with Instant Ocean or Reef Crystals. You can grab a refractometer off of Ebay for about $30 including shipping. I would go with the API Reef and Saltwater Master Test Kits. Just go with dry aragonite, I used 30lbs and have about a 2" deep sandbed. Just do a mix of live rock and base rock, half and half would work great. Get 2 50w heater just in case one fails. Thermometer of course.
As for fish, just go through the list that Krypt posted, most of the fish in there are compatible with each other, just post up a list here to double check it though. I would get maybe 3-5 astrea snails and 5-8 nassarius snails for a CUC. HTH
