Anenomes are trick at the best of times, I'd warn you against them until you have alot of experience.
In a small tank you have alot of options as far as lighting, it really depends on what you want to keep. My set up is lit by 6x55w PC's, & I find it is only enough to make softies really happy. My LPS are alive but I know they could do alot better. If i had it all to do over, I would save my money for MH's (250W or greater), or get a full VHO set up as I like the color alot better than PC's.
Heat is a problem that will plague you no matter what. I'm installing a free-standing AC asap for this summer. If that doesn't work I'll be getting a chiller for my next set-up.
