Hi moregood,
If I were you I would do it the other way around:
I would go over all the existing links asking the following question:
Is this an "editorial" link?
And I would cut out all the rest.
I think It's easier to find out the good ones. There are a lot of reasons for which links could be bad for you, you might not even be aware why they are bad. But the good ones are pretty obvious and way fewer :). I think it's easier to recover from a penalty this way, and the chance to cut something good is pretty low. If you go the way you mentioned and avoid cutting the ones that are in a gray area, you might resubmit the website over and over. It will take a lot of time. Meanwhile you could stick with the good links and invest the rest of time to get more of these
