These are the usual suspects to be rounded up. Be sure to note that '1' in the censor file means 'keep this time point', and '0' means 'ignore this time point'.
Some people think the file motion_SUBJID_enorm.1D is also useful -- it measures the size of the motion. However, I don't think it's particularly relevant for regression purposes.
Finally, some pedantic people object to the terms "regressing out motion" or "correcting for motion", since the effects of the processing don't actually turn the data you have into the data you WISH you had (e.g., without head movements). Personally, I think this kind of objection is pointless nit-picking, but you might run into it when you present or publish your exciting results.
