I enjoy the pattern books by Jennifer Chiaverini - I like the patterns, and I also like the tie-in with her fictional Elm Creek books.
For inspiration I love Country Living's Country Quilts (one of the first books I got, so may not be in print any more) and otherwise I just tend to delve into whatever looks good.
Have you tried the quilting/sewing section at your library? Could be good to experiment and see if you actually want to commit to buying a book (depending how up to date their selection is!)
