ahhh, duh! Dr. Pete shed light on what we should be thinking about here. You're not getting messages for sending out too much PR but for too many links. He's right; nofollow will not remove them from being counted. Nofollow stops PR from being passed.
Link equity is a broader concept than PageRank. Link equity considers relevance, authority and trust, link placement, accessibility, any value of relevant outbound links, etc. It sounds as if you need to focus more on how you implement the links on your site.
If you need to reduce links, as mentioned earlier, use AJAX as an external file if those links are needed on the page. If they don't offer any value, then remove them. I viewed your page earlier but cannot access it now. They didn't appear to help the user experience anyway. Often what's good for the user is good for Google.
