I know that the dorsal columns carry ipsilateral information. Is this fact relative to the dorsal column in question? If I want to talk about the right dorsal column, then the right side of the body would be considered ispilateral. But, if i then go on to talk about the left dorsal column, does this mean that the left side of the body is now considered ipsilateral?

Yes. Ipsilateral and contralateral always have to be relative to something; ipsilateral means "same side" and contralateral means "other side" - you can't really be the same or other side of something unless you have a reference point.
