You'd take the log of the Ys if you were looking for an exponential function, and both sides (as you suggested) if you were looking for power data. Also extremely common is inverse data, in which you'll just raise all of the X values to the negative first. You might also get inverse square, inverse root, etc.
Getting non-linear data is definitely a possibility. We also try to choose an experiment that'll give us linear data, but sometimes the experiment that clearly would be the best option involves a nonlinear relationship, in which case, you've gotta go for it. The transformations shouldn't be too bad, even without a graphing calculator.
Oh my, I really messed up my post (I was doing homework). The square root function is a power function. So you log the X and Y. And if it is exponential, you log the Ys.
