Looks like you have good start. Your temp should be around 78 degrees F. At this point I kind think your tank is has good start on being cycled since you purchased cured rock. I would throw in a raw cocktail shrimp and watch for your ammonia and nitrate to spike and fall to zero. Once that happens you will ready to add fish or corals. Just add them slowly. Each time you add something there will be a mini cycle. You will probably only want to have maybe three fish in there do to the size of the tank and low amount of rock/sand, and the skilter. I would recommend sticking to mushrooms and zoanthids due to your low lighting.
