Changing The Way MyBB Does Threads

[Seabody]

Should be viable to do it in index.php. Though my preferred method (and the one this was really designed for) is to put it in templates via PHP in Templates.

As for the postbit, create and modify a postbit_first template, leaving out what you don't want.

And for the thank you button, omit the button from the postbit template, and put it in postbit_first.
