Well, with a double t5 you are kinda limited in what you can keep. For sure no anemone with only 2 bulbs. if you go with 4 bulbs you should be good to keep a nem as well as a good selection of corals.
Some of my favorite corals that are easy and pretty are: GSP (green star polyps), zooanthids, toadstools, ricordia mushrooms, frogspawn, hammers and blastomussa. If placed higher up on the rock under 4 bulbs you could even keep some montipora. They grow soo fast and come in a few different colors like red, green and purple.
A great resource is Aquarium Fish: Tropical Freshwater Fish and Saltwater Fish for Home Aquariums
they have most every coral you could want and will tell you what type of lighting it needs and if it's aggressive or not. An absolute great site to learn stuff and find the corals and fish you like.
