It appears that you are "thinking thru" the process and that leveling the the frame is the correct way to approach this step. I didn't say before but assumed you have your drivetrain in? This would "weight" the frame and further help you to center the frame/body . I thought when I did mount my bodies, it was very helpful just to set back as far as I could and look to see the tire clearances. This will be one of your best guides and think of it this way , it will be the the way the car will ALWAYS be seen. One more thing, if you are using coilovers, make sure they are adjusted the same, allowing for tuning adjustment.
