Get an OMRON handheld bodyfat analyzer if you want to measure bodyfat. 2% margin of error, very non-invasive. Works well with your target clientele.
As for assessments, I use Motion DNA (3D functional motion screens), but not on everyone. It wouldn't be relevant with your crowd. Maybe do a squat to bench test (how many squats in 30 seconds.
I second the Gray Cook stuff... He's fantastic!
For the truly obese, I think you're on target to do girth measurements. Calipers and bio-impedance devices usually error out on the extreme ends of the spectrum because the algorithms are based on "norms," which they aren't.
