Forget the anemone in a 10g and this being your first saltwater tank and all.
Is there any way you could go with a larger tank? The reason I'm asking is that the larger the tank, the more stable it will be.
Okay, depending on what you plan to keep coral wise (NOT including anemones, clownfish do not need them to be happy) is what will determine what kind of lighting you will need. If you are going with a FOWLR tank (Fish Only With Live Rock), then you will be fine with the lighting that comes with the hood. If you plan on keeping mushroom corals or yellow polyps you 'might' be able to get away with the lighting you have if the corals are placed up high on the rockwork close to the lights. You could always add another regular strip light too. If you did this, you will want to get tubes in the 10,000k range or the 50/50 tubes. Now if you go for something like a hammer or perhaps a frogspawn coral, then you will need to upgrade to PC lights (Power Compacts). They come in either 55watts or 110watts, the more watts, the more money! I cannot suggest VHO's (Very High Output) lights as they don't come in tubes small enough for a 10g. MH's (Metal Halides) are the way to go if you decide to go with clams or hard corals, but they run very hot, and are very expensive to buy.
LR (Live Rock) is always a good thing to buy for any saltwater tank. If it was me, I would start out with sand for the substrate about 3" or more and around 10lbs of LR. Then I would cycle the tank using the fishless method, once it's done, then add the shrimp....make sure everything is okay for a couple of weeks then add the clowns.
Other things you will need are a heater, salt (ha!), a hydrometer, power heads and a filter (I will always recommend a filter for any salt water tank, you will get conflicting reports on this subject but I like the fact that they will remove particles from the water, you can run carbon in them and the added circulation. Just keep the filter media clean!) A good book is always recommended too!!!
Don't forget some snails like turbo and astrea.....maybe 5 or 6 total (turbos are clumsy and will knock over rockwork if it isn't stable) and you could probably add a hermit crab or two.
When you have inverts of any kind, it's always better to keep the salinity around the natural sea levels of 1.025. Also, most people keep their tanks between 78º to 82º temperature.
Can't think of anything else at the moment!
