Location of XML for watched/total-count on TV Show posters, and episode Ratings?

I’m new to Kodi, but I’d like to try tweaking the XML code to reduce the clutter in some of the TV Show posters and thumbnails. Specifically, could someone point me to the area of code which would allow me to:

1) Remove the internet-gathered Rating number which is shown within each episode thumbnail, as I really don’t care what other people thought about it before I watch.

2) Reduce the text content overlaid on TV Show posters – specifically to reduce the “nn / nn <eye-symbol>” in the bottom-right of posters to just the total episode count only. I mostly delete episodes once viewed, so all I need to know is how many items are available for each show. (What is the little eye-symbol there for anyway?)

Thanks for any pointers you might be able to help me with.
