Also, or maybe more specifically, a lot of the tools used to measure luma and chroma are in IRE but the 16-235 seems to be referencing 8-bit RGB. Just want to properly get my head around this, not just slap it in FCP and hit broadcast safe....
Color Finesse gives you scopes and a 100 page manual.

....which is the sledgehammer approach.
Even if you only have ONE oversaturated color -- the red in a logo, for example -- FCP sucks the chroma out of the entire shot. Better you should use Color Finesse or even Color, which comes with Final Cut Suite. Either one will do a fine job, and either one require reading and experimenting before you use it for real.
Thanks guys, I had already read through the Color Finesse manual. The controls are very simple and I was able to use it right away.
The main hang up for me at this point is that all the luma and chroma tools seem to be measured using the IRE scale. The particular deliverables that I have to give are in the YCC scale of 16-235. I am having a bit of difficulty finding a simple answer of how the two are correlated (look up YCC on Wikipedia and I feel like I am back in calculus class). Does anybody have any suggestions on further reading?
There is a HDTV 16-235 output colorspace in AE, but the AE colorspace is another can of worms.
In the after effects manual description of their own "Broadcast Colors" plug in it says:
"Note: A more reliable way to keep colors within the broadcast-safe range for your output type is to use color management features to set the output color profile accordingly, such as to SDTV (Rec. 601 NTSC). This method ensures that color values in the range 0.0–1.0 in your working color space are converted to broadcast-safe values. (See Broadcast-safe colors.)"
Does anybody have arguments for/against using this method to ensure correct broadcast levels? Changing to the HDTV (Rec. 709) 16-235 colorspace did mildly darken my project, but it is acceptable.

This should help: on a waveform monitor, 16=7.5 IRE Units (the horizontal dashed line) and 235=100 IRE Units.
On a vectorscope, chroma levels should remain within the circle when set to 75% Bars.
