I think Bryan Caplan talks about the Big Five some and is usually pretty clear thinking. He has a paper on the topic which gives some references for correlations between the Big Five and other things. For example:

A particularly noteworthy aspect of the Conscientiousness - job performance link is that Conscientiousness is highly correlated (.5 to .6) with various measures of educational achievement but uncorrelated with measured intelligence. (Barrick and Mount 1991, p.5) Conscientious people are more successful in both school and work. In consequence, rate of return to education estimates that fail to control for Conscientiousness are likely to be biased upwards.

And

Criminals are on average markedly lower in both Conscientiousness and Agreeableness than non-criminals, even holding other variables fixed.1 (Costa and Widiger 1994; Wilson and Herrnstein 1985)

I'd be interested in hearing if you find interesting results.
