1. What exactly is that 17 you changed to 11? Because I don't understand what you're talking about here. Still, this problem with PGE not supporting Fairy type is familiar to me. Do you have the latest version of PGE installed? I know this has been an issue in older builds, but now it fully supports Fairy type. I suggest downloading the latest version of the tool from Gamer2020's GitHub.
2. Can't help it, sorry.
3. Use Wichu's Advanced Sprite Editor, I'd say it is still the best tool for inserting Pokemon sprites into the game:

A quick tip: I suggest you'd better not use Mr. DollSteak's Rombase alone. Instead use this rom base:

It is built on top of Mr. DollSteak's Rombase and has a lot more features already implemented, as well as Mega Evolutions.
