I am still in desperate need of any help at all figuring out what the hell I did wrong.
The health cross floats way above players' heads (it also doesn't change colors with the state of their health anymore, like it used to), there's no health indicator on the person I'm healing. There used to be a standard health cross with a number next to it to the left of the "Healing:" that's just gone now as can be seen here: http://teamfortress.tv/thread/19073/hud-editing-short-questions-quick-answers/?page=24#703

This is my TargetID.res file here: http://pastebin.com/27m4y55K. I'm not sure what else to mess with as of right now. I have no idea what changed in the last three months since I last touched TF2 to make my HUD do this either.
