Do I need to add flash exposure compensation to make up for the loss of light due to the additional distance (up and down versus straight on) and diffusion of light from the flash? Is there a general rule for how much to add?

When bouncing flash, I almost always add +0.5 to 1.0 exposure compensation. You can also try increasing shutter speed, iso or aperture just a bit, if +1.0 exposure compensation isn't enough.
