This has been a useful topic for me, thanks again!
1. Should a character's good save be successful 50%, 75% or 95%?
Good saves on average should be about 2/3.
2. Should a character's bad save be successful 5%, 25% or 50%?
I'd say about 1/3 up to 1/2.
3. Should character DCs differ from monster DCs? If so, by how much?
I think that monsters and characters at the same CR should have similar saves.
4. Do your opinions about how saves/DCs should interact differ from your experiences of how they actually interact? If so, how?
I think brutal instant kill effects should maybe be easier to save against, and less powerful effects should have something other than just 'no save'. In my experience, save or die is fairly lame and should be hard to pull off unless a character/NPC/monster really makes sacrifices to strengthen that ability. On the other hand, I think that spell obsolescence is not so hot, weaker spells should have some way to remain at least somewhat useful at higher level, so I figure their saves could become more difficult.
