Lily Chin wrote a book called "Knit and Crochet with Beads". You might find that useful. None of the patterns really grabbed me, but there's lots of info about technique.
I am working on my first beaded project right now. It's the bikini in the newest Vogue knitting issue. The yarn is Lana Grossa's "New Cotton Print" (6o% cotton, 40% microfiber) I'll be putting pink seed beads around the edges as trim. Maybe I'll get it done before December....
Have you read the Knitty article on the subject by Sivia Harding? It's fabulous.
