I tend to agree with the concepts of moderation, diversification and the regular addition of unique content providing stability in the SERPs.
I mildly disagree with the directory aspect. Historically, a DMOZ listing would lead to a site being listed in "B" or lower grade directories using DMOZ as a seed. To the best of my knowledge that never hurt anyone. I'm not opposed to one way links from smaller directories, but I'd never link back and I do look very strongly at review fees if they are charged. A $5 review fee isn't somewhere I want to be, if it's more than $30, then I'm going to look a lot closer at overall value. I really don't see a downside as long as it's part of an overall package and not the exclusive method of link building.
