Just wanted to comment on an earlier point when Techen said that cleaner shrimp weren't part of the clean up crew. It's because people assume they clean the tank and hence the name which is untrue, they are named as such because they clean the fish.
Not all fish are so happy to welcome the advances of the cleaner shrimp, I'm certainly not surprised by wither of those species

Gobies keep themselves to themselves and firefish seem fairly resilient to external parasites, it's mainly angels, tangs and anthias that get the good cleaning. I have a big Bicolour angel at work that loves the cleaner shrimp so much I had to add a few more as the angel wont leave it alone and wants constant attention (got paranoid and FW dipped the fish for parasites and no obvious ones came off, I think it mainly just likes the attention!).
Also with the corals, I am not entirely sure I would recommend a Cataphyllia as they get huge and pretty quickly, found them to be quite aggressive as corals go as well. I would personally start with a few much easier to cope with corals like the softies (mushrooms, riccordea, zoas, xenia, green star polyps or toadstool corals) <-- last three are in Techens tank

and then move onto hard corals which are much more demanding and temperamental. Duncans Coral is pretty easy to keep and looks lovely (for a hard coral that is).
Also, I have found for the goby/pistol pair, it really helped to have a little offcut of pipe (at the shop I cut 3" of 32mm black ribbed pond hose) and I half buried in into the sand and piled more sand over it and a few little rocks over it too. The goby and pistol went straight in there! Means I can decide where they live rather than them finding some little hole out of sight at the back of the tank.
Another this, if you have a choice of Pistol Shrimp, get the Randalls or Tiger Pistol Shrimp, they are stunning!!
