SWEET! Sorry to hear your Jeep got smacked but man that awsome they say it's repairable. Rare with frame damage.
Yes definitly get it in writnig and get a DEALERSHIP quote to fix it, hell get 2 dealer quotes.
My buddy Erics 2001 Tacoma got smacked and bent the frame as well. The insurance co shelled out 16 grand to replace the frame and right front a arm. Frame was 4K, a arm was 800. Him and his dad did the rest throughout the summer.
