Stick to DMC threads love, much easier to find. This site will give you some idea of what colours you need :

As for the Rainbow Gallery Petite Treasury Braid, I found this conversion to Kreinik threads http://juliesxstitch.com/stitching-t...nik-conversion Lakeside also sell the Kreinik metallic threads. Use the braid in short lengths as it has a mind of its own and splits very easily.
