I'm a long time Perl programmer (and many other languages); I just started programming VBA in December. I've been mostly relying on Walkenbach's "Power Programming with VBA", which is great. To a lesser extent, using "MS Excel VBA Programming 3rd Edition for the Absolute Beginner", (Birnbaum & Vine) which is so-so.
Just browsing here has already helped me a few times.
