This comes more from advice I've been given than from successes of my own, but:
Since you're experience has been in management, a big aspect of advancing your career is likely going to be networking. I've found that resumes and payscales really only outweigh networking in certain fields. If what you're selling in yourself is your experience at dealing with things, dealing with people, and dealing with problems, you're only going to get that talent across in person. So, network. And that includes both inside and outside your company. Talk to supervisors, bosses, admins, whatever, and attend conferences if possible (I know from experience this one can be hard if you're on a tight purse string already).
Point is, once you're into management and admin, your career starts coming from you, not your resume. Hope that helps a little.
