Need help to setup a135 Gallons Saltwater for Newbie.?

I have a 135 Gallons of tank and planning to make a saltwater aquarium. I already know the mixture for the saltwater. I would like to put some fish like the Clown fish and some peaceful and colorful type of fish from Finding Nemo. I'm planning to put the fishes in pairs per type. I'm going to put live rocks on it and an inch of sand at the om. Now the question is, what type of filtration system should I get? Any brands and model? Also what kind of protein skimmers? How many fish can I put on my tank? How about if I put 3-5 corals? Also what kind of power head and the lighting system? My apology for having a lot of question but I don't want to learn from my mistake. Thanks for all the advice.
