I've got an old Dungeons and Dragons map from I was a kid and I'm trying to remove the drawing/pen (which is black/grey at varying degrees) from the off-white/blue-grid-graph-paper that it was drawn on. What's the best way to go about this?

If you posted a snippet of the image it makes showing easier, since people can use that for examples.
I would likely start with the select by color tool and play a bit with the Threshold to select and delete out all the blue. Then try the same with the off white. You'll likely need to be more careful with the off white as the greys from the drawing will start to get selected at some point. You can try copying the layer and multiplying it over itself to get more contrast if the original is faded.

I've added an image to the OP...I had to reduce the quality to meet the forum upload max.
There are ways, but you'll avoid yourself a lot of work by taking the picture (or making a scan) again with a more even lighting (don't use the phone'ss flash): take a shot near a window or in a brightly lit room. As it is there are parts of the white that are darker than the blue lines in other places.

That was what I wanted to comment on. The lighting used in this image makes this task not only more difficult but contributes to worse results.
Homogenizing the lighting would be the first step for you to get a better result.
I think I would skip worrying about rescanning and just throw a transparent layer on the top of it and retrace it in GIMP. I did this in about 5 minutes, you could do much better in 30 and have something that would work.
