Anenomes would be the sticking point there. They require intense lighting, and very pure water. (You shouldn't get one at all until the aquarium has been set up for a year, even if you have all the best equiptment.) If you want to start out with anenome supporting light so you don't have to replace it later, you need to look into VHO (Very High Output florecent) PC (Power Compact Florecent) or MH (Metal Halide) lighting.
VHO is probably the easiest and cheapest for a do it yourselfer. The long bulbs give a very even lighting to the tank, which appeals to some people. If you go this route, I recomend you splurge for the Ice Cap ballast. A higher quality ballast will save you electricity and make your bulbs last longer.
PC is easier to find in complete hood kits, for people who don't want to look at wiring diagrams.
MH will give you the most intense lighting you can get in a single bulb.
I suggest you browse around for fixtures in the 300 Watt range of all three types and decide what your budget will support.
