I'm pretty sure all those .idx files are for the 3d models (things like the map and objects) that get cached when you use signed to make it load faster. If you use unsigned, every time you get to a loading screen you have to download those files and put them in your RAM, which makes your compure lag more.
If you're interested Silabsoft has a 3D Model Viewer for the RS cache.
Oh, and the UID is just a number for tracking you and your accounts. I'm assuming it's so they can IP-ban more effectively something like a packet bot ever comes back up again. I personally delete mine each time I load SMART
