Holy crap, for those of you that may not be aware, If you're retexturing, whilst rescaling lots of stuff at a time, there is another way than CTRL-selecting a bunch of stuff and then adjusting face properties.
At the bottom of the face properties window click the 'mode select' and choose 'apply texture and values.' In this way, you simply click on anything to be changed and magically, it is done! Much easier this way IMHO. I never bothered to see what that little mode box did before!
