+1 for Standing in the Shadows of Motown.
As far as technique (as in, how to properly move your hands and fingers) I highly recommend finding a good instructor in your area and at least taking SOME lessons. He/she can look at your hands and tell you HOW you are wasting motion, not getting your fingers in the right position, or what to do if you have hands shaped differently than your favorite bass player.
For instance, using "1 finger per fret" on the low notes is a good way to sprain and maybe permanently wreck your hand, unless you have large hands. Try using your pinky and ring finger together as one finger - use your hand like you only have 3 fingers and move your arm around more, instead of noodling on the entire fretboard.
I'll get back to you on books I've found useful. They're in a crate at my temporary apartment. Ha.
I will say this, tho... I don't recommend going with one teacher/book series. You'll probably just end up sounding like a pale shadow of that person. Try a book from Mel Bay, then a book from Hal Leonard, then a book from Josquin des Pres, etc. Mix it up, get the gist, and then start trying to apply. Don't just "copy and paste." I think my first two books were Josquin des Pres. I was half way thru the second before I said, "These feel like the exact same grooves." So I listened ahead to the CD, compared it to the first... They pretty much were the same book.
Tension and release. Point and counterpoint. Funk 'n' jam and groin shaking walls of bass.
