Actinic is very good for coral. it's not the best for direct growth, but it gives it a more full wavelength to photosynthesize. 10,000k is a very white light, and you will lose a lot of the pretty colors you see on the corals. When you go and see these beautiful coral aquariums they generally have a white wavelength of 20,000k, which is more blue. For a 30 gallon tank you need more than just a two bulb fixture anyway. I'd junk the light or return it and get something better. You can fine awesome deals on craigslist and different reef forums.
Zoas are the clusters of tiny polyps. Mushrooms are just that, they are colorful mushrooms of different textures. They are both soft corals so they don't need a ton of flow which is helpful. I'd have about 600gph flowing through the tank, maybe using two smaller powerheads going in different directions.
