Yeah I'll look into making an IDA tutorial or something similar.
There's actually no documentation of it unfortunately. People have discovered it (otherwise we wouldn't have tools that edit it), but no one has posted their findings for some reason or another. Anyways, the steps should be the same. Make sure you see the class name on the screen, THEN do the "fh" thing to find it in RAM. Alternatively, like the trainer names, the class names should also be in a table in the ROM. So if you try and find the class name in a hex editor, you should be able to find the table (very easily).
From there, set a bpr at that table for 1000 bytes. That should get you some results :)
