So, after completing the rest of the PT I only noticed one relevant difference between the original and the dub. In Clones, the awkward "I wish I could just wish away my feelings" was altered to "I wish I could just wipe away my feelings", which is, in my eyes, still a bad line, but the best someone could have done without changing too much.
Other than that, Clones and Sith really were as bad as I expected, not seeing them wholly for some years didn't prevent me from being outraged at every character's stupid decisions.
@darklordoftech: Thanks, I made the avatar in 5 minutes using paint and google image search. I didn't even notice how well the shadows of both parts match :)
