For getting your VBA questions answered, you'd be hard pressed to beat this site.
As for books, these are 3 that I use:
Excel 2000 Power Programming With VBA (John Walkenbach) -- there's a 2003 version out too
VBA and Macros for Microsoft Excel (Jelen and Syrstad) -- from MrExcel
And, for further down the track, Professional Excel Development (Bullen, Bovey & Green).
General web resources: Chip Pearson, Stephen Bullen, Tushar Mehta, John Walkenbach, Jon Peltier and David McRitchie (among others) all have good sites.
Hope that helps
