Most anemones require HIGH lighting!! What kind do you have?? I'd consider returning them to the LFS.
The inhabitance will dictate the lighting required. For 300$ you could get a nice Power Compact, VHO or T5 fixture which would allow you to keep a wide verity of corals and such.
How long is the tank?? If it's 36" then a power compact with 2-96w bulbs (less than 200$) or a VHO with 2-95w bulbs or T5's with 4-39 watt bulbs (less than 200$) would all work. With these you would be able to keep about everything except anemones, clams or sps corals,
