Kay,
I would leave the removal to the interior specialist. They are going to have to remove all of the old adhesive anyway. And while you are at it, make sure the shop has experience with this dash, it is very difficult to get right. Typically the leather has to be shaved thin enough to get it to stretch properly around the curves in the corners. Then a flap of leather needs to be left on to allow correct installation behind the air vents.
Best,
