Riven's training has been done with positive reinforcement and the clicker and he has turned out quite well if I do say so myself. ;)
All the books you mentioned are outstanding resources, the only one I would add would be Sheila Booth's Purely Positive Training.
Here's a link to a short article I did on getting your rottie started in obedience. It covers what to look for in an instructor.

The sooner you get started in a great class the better!!!
Good Luck!
