I'm a huge fan of nice halogen lights. The CRI on anything fluorescent or LED is going to be much more costly over equivalent halogen / incandescent lights. I love the warmth and color that a good halogen can provide. There are even some paintings that require a halogen for maximum art factor. (think 'peter lik')
As far as lighting layouts go? Up to you. It depends if you want shiny light or a soft diffused look. If you want 3 point lighting or spot, it's really up to you.
Now IIRC, code is a bit weird when it comes to efficiency.. so make sure you have enough LEDs to compensate having some non-efficient lighting.
