Three clownfish is going to also going to cause you problems. Two will pair up and the third will be turned to chum.
Before you contemplate corals you need to get your stocking levels way down. Maybe 6 fish (and only 1 or 2 damsels only)
+1 you're way overstocked, and thats why the tang died, also because it was in a tank much too small for it, they need a tank that is 6ft long at least for them to swim.
all of those fish and other inhabitants (with the exception of the star possibly) are reef safe, but crepe hit the nail on the head with the problems you'll certainly have.
but as for lights i'd suggest looking into a nice 4-bulb T5HO unit, it wont be very cheap, but it'll be able to keep what you want for a starter, i'd look into fishneedit.com, they have some nice units for good prices.
