There is a new DVD set on Chair Caning that I wish was around when I was teaching myself to restore chair seats. The four DVD set ($79.99) covers the 7-step method, pre-woven cane, fibre rush, and splint-type weaving. If you only are interested in one aspect of seat weaving, you can buy any individual DVD ($24.99).
As for books, I can personally recommend Seat Weaving by Ricky Holdstock and Chair Seat Weaving for Antique Chairs by Marion Burr Sober. The former is a great resource with lots of pictures. The later is a 64 page booklet with line drawing diagrams, glossary, and easy to follow instructions for hand caning, rush weaving, splint weaving, and Shaker tape weaving.
Here are some online resources for instruction:
