My guess would be that when you switched scrapers, you would have been given the option to refresh information for all items, and you chose 'no' (because you only needed a few things fixed.) This would have also left the TV show information (where the episodeguide URL is stored) unchanged.
I'd suggest going to the Highschool DxD folder (in library or file view) and refreshing the information for whole show (press 'i' while on the folder, select refresh). That should put in the right episodeguide URL. You can choose to not refresh the episode info, if you want to keep the tvdb-scraped episode info, but you might then have to manually refresh the special episodes to get them to use anidb.
If you only changed to the anidb scraper on that one show, that should be it. If you changed on the root folder, then all your shows will have the wrong episodeguide URL.
(You won't need to switch to the newer anime-list.xml to get episode information for Highschol DxD, but it's still a good idea. It's a lot more up to date.)
On the third issue, you will likely need to add a new tvshowmatching regexp if you plan on dropping the SxEE from the filenames (or hope that they'll be ignored in favor of the absolute number).
