Without me having to look what is the ATA supposed to be? Bear in mind that these measurements are not absolutes. They can vary some depending on how you twist up the rigging to make the bow suit you. Did you install the length string as called for? Make the bow fit and let the measurements fall where they may, so long as they aren't too far off.
As for cam lean, you can reduce it somewhat by adjusting the cable rod so there is a minimum of cable clearance with the fletching. Anymore than about 1/8" extra is not necessary. All it does is twist the limbs.
