I'd use jQuery for validation.  There are some nice tools available,
depending what you want to do.

I haven't been very happy with modifying WP E-commerce.  It seems the
code is rather messy and hooks are often lacking, and I've encountered
a few surprising things for a product that's ostensibly quite mature
and very widely used. There's no doubt it's flexible -- probably the
hands down most flexible tool out there for the very reasonable price
of free+paid extras -- but there have been enough emergency updates
that I'd definitely not want to impact my update path. I've been
looking around for an alternative and currently have Cart66 on my
testing server.  The code seems clean, at least so far.
