I did find a quick and dirty fix how to export patches without typing them a while back. Reserve your page of memory type your patch in, then go back to the memory and change your reserved page to a sprite, then go to the sprite editor and export your sprite. Then paste it into whichever game file you're using (It's easiest if you paste into the same address as the other file, but you don't have to, and you can always go into the hex editor and change any numbers you need to).

I can't answer about the data in that page? Best ask John about that one? But you could always just reserve another empty page for your patches (unless of course you specifically want them as close to each other for managability or saving space?).
