I'm pretty sure I've fixed everything you've listed so far except for dialogue-related things, I did fix some of those but never bothered inserting them because of the way the script is divided, I haven't come up with a good way to do the pointers yet.
Looks like I haven't posted a patch in a while though, I'll make sure everything listed in this thread is in the latest version (I'm 90% sure it is, I was just waiting for another patch request) later on.
My working directory was a bit of a mess, I did the battle fixes in one ROM and item fixes in another. I copied everything over into one ROM so it should be good now, just let me know when you want a patch.
