Congratulations! You just won the saltwater game. You can use stock lighting, don't require a sump, fuge, skimmer, or anything else overly expensive. Research live rock and find some, or dry macro rock, for your tank and some sand. Add a small powerhead for some flow and you win. The rest can easily be answered by the articles listed above. While you cycle your tank, you can research what livestock you'd like in your 30 gal.
The only downfall here is that you will find many fish you wish you could have but require a much larger tank. Whatever you do, don't look into any corals or you will be hooked and require all of the things you don't need. Lol.
