Just to update... I downloaded that google drive for desktop app. Google Drive on cloud says I have 215G in pics (all aggienetwork google drive, not google photos). When I look at Google Drive desktop, it says 180G, not sure what is up with the disparity. Regardless, for my first step, I just initiated a drag and drop to my desktop (this is what I was wanting... simple drag and drop, with the same file structure etc, so will be interesting how that works). For time remaining (its only been 10 min or so, it says "more than one day." After that, I am going to save it to a 250G flashdrive for redundency until i figure out why google photos won't let me give them money for more than 100G... I guess I could split them between two accounts, figure it out with India tech support, or go with another cloud photo storage service.
