If you do all of this, do you remove all the data on your ipad? I don't want that happen

Yes. There isn't a way to recover the data from a disabled iPad.

Too late for that, now.

If your iPad went into restore mode and you have never made ANY data backups of that iPad, all the time you have owned this iPad, then it is, now, too late and that data is already gone and gone forever.

Sorry.
