Can I chime in too? It might help to watch Amy's dpn video if you're unfamiliar with double pointed needles. If you've already mastered the circulars then you're pretty much there! My preference would be to slip all stitches to 3 dpns and then continue.
And you probably want to transfer your stitches to dpns sooner next time--you don't want to have to stretch the yarn to connect around the circs.
