All right, I've uploaded it to http://www.filedropper.com/setup-bg2tweaks
(no idea how long will it last there, if the link won't work, let me know and I'll reupload it or figure something else out)
BTW, since some things seem to be fixed already, do I need to remove and fresh install the mod, or is just running it again to install the parts that didn't work (or new parts, like shops buying everything in BG1) fine?
