I haven't studied it much, but LED's are the way to go. Last forever, and use 1/10 the energy of similarly lumen'd CFL.
I would look into putting in a gutter all the way around, have the LED's behind the gutter, reflecting off the ceiling.
There are some manufacturers of LEDs that are starting to get into the normal color temperature range we are used to, though pricey. I bought some soffit-type LED's for my kitchen redo, and they were the color corrected ones. About 3 times the cost of normal LED's, but they do not produce a harsh color temperature.
<edit> contrary to popular belief, I really do believe in conserving energy where it does not interfere with my fun....
