Hey all,
So, the shop called with an update. They got the 300 on a lift and pulled the lower panels to get a good view. Like Can't Know and Husky Man suggested- the radiator support was bent enough to lightly damage the radiator (causing the drip) and pushed it just enough so that the fan blades could rub (causing the noise). As for the tranny- he said the lines might have gotten slightly bent but it drove into the work bay without any problem at all.

He commented that without removing all of the panels, you couldn't see where the radiator support had been damaged. So- I'm now thinking the PO must have smacked something to damage the support- and my light bump against the curb finished it off...
