If you want to keep anything, you're looking at around 1,200wts total
I would personally go for 2, 400wt 20,000k Radiums and a single 400wt 6,500k Iwasaki, which will be great for the more light demanding clams, which do better under a 6,500k spectrum rather than the 20k. You will not need any actinic suppliments. Heating will probably not be an issue. If you want to, you can make your own (or have someone else make you) a 12" deep canopy, which will house the halides. Also, 4, 4" NMB fans (can be bought at home depot) mounted into the canopy would really take care of the heat, so I doubt will you ever need a chiller, unless your rooms are hotter than normal.
You can go to the Reeffanatic Store, which is close by, and buy the halides. Hello Lights also sell the halides, for around the same price. The total should be around $750.00 or more for the lighting (includes reflectors, ballasts, sockets, disconnects, bulbs, etc.). 600wts really won't get you much, you wouldn't be keeping everything as healthy as it would be, with lets say 1200wts. You can get good deals here:

1, 400wt 6500k Iwasaki Halide:

Remember, bulbs would be 20k 400wt radiums, and a single 400wt 6,500k Iwasaki. You don't have to order it, since the store is close by (about a half an hour away). Shipping would cost quite a bit, considering that 50lb PFO HQI ballast, as well as the other ballast. This lighting is outstanding, and you would be able to keep nearly everything (The reason I say nearly, is because some corals just don't survive in captivity. Lighting won't get you instant success, although it will help).
Also, leave off on the anemone. They have horible survival in captivity, and most don't live longer than 3 months. If you have to get one, I would wait until your tank is older than 6 months old, as well as have the proper tank conditions, inhabitants, and knowledge to care for one. I would personally go with the Bubble Tip Anemone, which seems to be doing the best of all anemones in captivity. Most of the ones you see at the pet shops are bleached (Lost their zooxanthellae, and completely white), which will be very hard to revive it. Go with a captive raised one. There are many people selling these for very cheap!
You also might want to think about a calcium reactor later on. Some people can make one for you for around $150.00. I must say, Larry (Hawkdl2, on --), makes outstanding reactors! This is not a must, but it's recommended, esspecielly for clams and small polyp stoney corals (SPS). You might not even need the UV sterilizer in your tank. While it is getting rid of some harmfull things, it will also get rid of good things, such as pods, some worms, etc.
As for the Aquatic Outlet deal, I cannot agree with you more!!!! Over priced equiptment, bad advice, bad livestock, etc.
I attached a picture of a High Grade Crocea clam, which you will easily be able to keep under your lighting (as well as good calcium levels, good nitrate levels, steady temp/salinity/pH)
