Rear camber adjustment

[Ender]

Ok, I think I'm gonna go ahead and fix this in the next couple weeks so I can travel with the '7 without destroying more tires, and so I can get better grip. I think I'll buy all three of these products:

I could buy the the adjusters and/or the camber rod from Mazdatrix and the spherical bearings from AWR, but that will incur another shipping charge and the totals without shipping differ by only $15. How necessary would the zirc fittings be that Mazdatrix supposedly puts on the adjusters?

Another question is: will a shop be able to competently align the car with these aftermarket parts installed? The whole point of this now is getting the alignment set up properly while avoiding suspension binding. I understand the principles here, I just don't feel I have the proper resources to fine tune it myself. Perhaps, if I knew how to quantify the adjustments. Can you set up camber very well with a level if the car sits 'perfectly' flat? After I install these parts could I put the rear on my ramps and adjust the camber myself? I'm thinking I could, but confirmation would be good.
