Thanks for the info. I am being convinced more and more. I have a feeling my desire to have them soon will override my worries about lightweight, flat, flexible pieces of plastic coming off my car.

Yeah, the upper grill with the H logo really makes the air dirty. I had coated mines in black duct tape and it made a bigger difference than I would of suspected.

The data on tirerack says the stock tires for my car of the type I'm looking at have 808 revolutions per mile, so at sixty miles per hour or one mile per minute, that's 808 rpm. Doing the math for outer tire diameter, and doing the math for engine speed/gear ratios, works out too. And I'll occasionally be going 80 or faster to keep up with traffic so I'm not a danger to everyone else on the highway, so it'll need to hold up to faster than 800 rpm.
Yeah, the engine bay is pretty bad for aero, period. The more air you can manage to keep out of there (without overheating anything), the better.
