C Witt,
I think it's really more a question of your experience with autolisp/vlisp rather than "current" book.
AutoLISP Programming Principles and Techniques by Rawls and Hagen is excellent if you can find a copy. Though I believe it's out-of-print, Borders often has it. It only covers AutoLISP up to R14. Still, I wouldn't be without it. Granted, I'm a book freak.
