Chess, you place great emphasis on avoiding a highly reflective screen(don't want to shave while watching TV, eh?).
This article from CNET examines the issue and notes that the only plasma with a matte screen is the LG which is reviewed in the Sound&Vision test you link. It's only in 50" or larger if you still decide that's too big.
Otherwise, there're various Panasonic(as mentioned by Hellcommute)and Samsung models in the 40"-50" range tested and recommended in the December issue of Consumer Reports.
As to trying to angle it downward, sure, it's an angle of incidence/angle of reflection thing.
