Also, thanks for the PM, I'm here anytime...
it's kind of hard to diagnosis what your mechanic is having a problem with, without actually seeing the problem or having more details. My guess would be that because our cars are only adjustable through the toe, as long as an alignment is concerned, that the mechanic worrying about the camber not being in stock specs? If i were you i would take it to another shop and try and see what they say... As Eric mentioned, it may be that the installation of the of the strut hat isnt tight, or some minor installation error is throwing off the alignment... If you can find out more information on what exactly is wrong, we would be able to help you a bit more but as long as camber plates go, you truly do not need to install them with your setup. Unless you plan on adjusting camber and such for racing reasons, it is unwise to have them on a street car. Turner does not have to be your only source for parts (although i personally like them alot). I would also look into Ground Control as well as what Understeer.com offers.
Before all others of course it may be wise to check out the werkz vendors and see if they wont cut you a deal on some plates. but once again, i highly doubt they would be needed.
