So, ignoring that Jake and Dason and hlsmith know what they are talking about, how does one interpret the impact of a predictor that has a non-linear relationship to Y? Just run the regression at certain levels of X?

The key thing is to make sure you aren't over fitting the curve. Remember, you CAN get point estimates and predictions from the model GAM, you just don't get a single coefficient, since the relationship isn't linear.
