No, the 40.0 isn't backlit.
Just about any Dish remote will work on Hopper/Joey in IR mode on address 1. But I can't think of any reason to do that. The 32.0 will work on Hopper/Joey in RF mode, which is quite useful since used ones are quite a bit cheaper than 40.0's.
Only the 40.0 is 100% compatible since it's the only one that works with backup/restore. The 32.0 does everything except that. The 21.1 and lower only in IR mode and don't backup/restore or locate. The 6.3 and similar also work in IR mode but are missing the 4 colored buttons.
Just about any universal remote will work in IR mode using the standard Dish address 1 codes that have been around for years. But they can't learn from a 40.0 or 32.0 because those can't send Dish IR commands. So a 21.1 or below may be useful for teaching purposes in case you have an old universal that has no Dish codes or may be missing the colored button codes. The pronto hex and JP1 codes have been posted a few times and should be easy to find.
