+1 on the above. It's pretty hard to kill the soft corals like the Palys, zoas, mushrooms, green star polyps, xenia, and kenya trees. They grow almost like weeds in some ways!!! I just started my tank a few months ago and I started off with some basic stuff as well as some LPS and now I have some simpe SPS in my tank like birdsnest and some hardier Acros. They seem to be doing well. I think you should do a combination of the softies, LPS, and a few SPS. Since the SPS grow so slow relative to the softies so it's nice to have some relatively faster growing stuff(xenia, kenya trees, etc) and some slower stuff like the SPS to try to experiment with them and see how they do in your tank. After you get the hang of getting your water parameters in line and get into a good routine, you can gradually change the various proportions of each type of coral in your tank. Be warned though that things like mushroom really multiply quickly and you might end up having to pull them out later so don't go hog crazy on buying too many of them. It's easy to get rid of Kenya trees though when you want to pull them out. All I'm saying is to think long term where you'll want things when buying stuff
