			I would like to recommend a new textbook called "Japanese Step by Step" by Gene Nishi  2nd Edition published in 2010 by McGraw Hill.  I like the way the author uses diagrams to explain how verbs  are derived - they seem to stick in my mind better than other explanations.  Verbs are grouped under a,i, u, e, o format with u being the dictionary form, which the author calls V3 as u is the 3rd on the a,i,u,e,o list.  Chapter 6 contains 13 uses of V3 with examples.  Lots of other grammar as well - good for beginners or advanced beginners.
