The tire shop will be able to look up the stock settings for your car and will get you as close to spec as possible. Any suggestions to them, to try and go outside those specs, will be met with an explanation that it will decrease tire life. Just a call you have to make.
By nature, the car will like to wear at the insides of the wheels....more so in the rear than the fronts. From my experience, the fronts see the wear on the outside shoulders, from cornering. So as long as you are good about rotating them, you should be able to keep them relatively even.
