Do you need actinics? No. Will they give you more blue? Yup. I use actinics for a dawn/dusk effect, plus it adds a bit of blue to the tank. Personal taste will dictate what you need/want/buy.
For the FO tank, you need lights that let teh fish see and let you see the fish. Beyond that, again, personal taste. It doesn't get more specific than that.
