I would not go a kit route. You'll have more fun doing it yourself.
I would stick with the 2smd or single 5050(5mmx5mm). You can color match green and blue but just using cool whites and warm whites usually works out well. That's for inserts.
GI you should likely want warm White to match the art work better.
If your not sure do a small section at a time.
Comet has a good reputation.
