I'm currently working my way through Kirkpatrick and Feeney's "A simple guide to IMP SPSS Statistics". Like the title says, it's very simple, at times, too simple it seems. But so far, it's been a great way for me to get reintroduced to SPSS. It walks you through both the point-and-click and the syntax methods, and includes how to conduct various procedures (t-test, ANOVA, multiple regression etc). There are great screen shots of what you might encounter.
I also picked up "SPSS Essentials: Managing and analyzing social science data". I haven't opened that one was yet so maybe someone else can chime in.
