Greg--I think all of those things change slightly, but not dramatically. I can also front squat, overhead squat, and deadlift with no problems. My deadlift is substantially stronger than my squat, if that helps clarify things. I also have abnormally short legs for my height (inseam 30", height 5'10"+).
Here's a photo. This is on the way back up. Bottom for me is a few inches lower than this, with the top of the thigh at or just breaking parallel.
