1) Is there a way to drag/drop reposition a background image?

Doubleclick with right button

2) Is there a way to make images transparent? I tried fiddling with the gamma slider but it did not do anything for transparency.

3) Is there a way to crop off arbitrary sections of a background image? Some of the sketch pages also have cross-sections, and those will seriously confuse things when trying to place objects. I would like to crop them out.

You should do it in external photo editor but in xTherion you may easy switch order of background images.

4) Is this something that I need to do in an external image editor like Gimp? I have not used Gimp in several years. The learning curve is daunting.

Try any simple photo editor - most of them are able to crop a part of image.

and many more.

As a tip: compile with sketch included as .xvi may help you much.
