I disagree that seoskunk's list is a good place to start. Your statement that "the quality of the links matters" should be the "good place to start".
Quality is always in the eye of the beholder, if you are specifically looking at rankings in Google, then the focus should be "what does Google consider quality in this niche?".
While I personally think people shouldn't pay so much attention to what Google representatives say, most webmasters probably shouldn't be using the disavow tool. If you did some really outlandish things and got smacked, by all means, use it for a comeback.
If you are looking to move from page 2 to page 1, that's probably not going to be that thing.
