Some of you guys need to really get out more. Yes, a lot of the romantisism of crouching dragon esque shit is completly legend and made up. I have seen and practiced with these guys when they toured the states. To be fair, Martial monks are the real deal. There are monks who are not nearly as skilled and train and teach at the National training Center and they mainly do what is refered to as Wu-Shu, more of a Tae Kwon Do watered down style (what you would see at a National Tae Kwon Do / Karate Do tournament) The paul mitchell bullshit tournaments come to mind.
Regarding Chinese and groundfighting, Shuai Chiao has practiced since ~300BC. Also see Chin-Na (joint locking and muscle tearing). No, not every style has or uses groundfighting skills, mostly the Northern Styles stay away from groundfighting.
Most Americans will not endure classical training, so you will not see much crediable instruction in the states, but there are some out there(very, very few).
