Revup - I got my 5D3 last week from J&R. I called August per your suggestion and was able to get a $150 discount of the camera. Thank you for that...
Its really difficult to explain how to do what you want, there are so many different ways to achieve the same thing.
The following is for RAW files. Jpegs do not need camera profiles applied.
G0 to a imported raw image, highlight it, and go down to the camera calibration section in the develop module. Click the drop down selection in Profile where it says Adobe Standard and select the profile that you set in your camera. Try the different profiles to see which is best. Then, adjust sharpness, NR, and the other sliders for the best image.
Setup your options, in edit / preferences / presets. Check the appropriate blocks to make your default settings specific to a particular camera, a particular ISO, or for all.
Then, click develop / set default settings / update to current settings.
Now, when you import a raw file, it will receive those settings, or the settings for that camera / ISO that matches. If you set it by ISO, you will need to set the default import settings for each ISO. This is only the beginning, since you can create and apply presets galore as well. It literally takes a book to cover it well.
I've personally been buying from this store since the mid 70's. I got the Canon 5D Mark iii with kit lens for $4169 $130 less than all other retail stores through the sales rep named August. They are in NYC and their number is: 800-806-1115. I had asked August if it were OK to publish the price he afforded me on this web site and he had said OK. His extension is 1041 but you will need to ask for him personally.
In addition, J&R just posted a $400 american express rebate when you buy this camera with a PIXMA Pro9000 Mark II Printer. The printer is $299 so you actually can make an extra $100 in savings after you mail in the rebate.

Hope that helps everyone.
