On the DAT will we have to decipher between an aldehyde and a ketone and an ester? The characteristic C=O bond around 1700 is present in each, how do we determine the difference?

That's unlikely. But you may be required to distinguish between carboxylic acids and aldehyde, ketones, and esters. So, they all have a peak at 1700, but carboxylic acids also have a broad peak at 3300, due to presence of OH.
