I consider CVs and resumes to be the same thing, just that a lot non-North Americans call them CVs and North Americans tend to call them resumes. Maybe in academia it's different? But I've never looked at CV's as containing anything different than a resume. I'm uncertain how much you want to cut down, but I would say that obviously two pages is the bog standard and anything more than that might not get anything more than a cursory glance.
Thanks everyone for your helpful replies. For those of you who did have publications, did you include these on your honors and awards?
