Need expert advice on Oslo repair

Last fall I noticed that my burner tubes were a bit off. Left side is about 1/2 inch higher than the right. Noticed it last fall but ran it anyway. Must of jammed a log to hard in there and bent something. I noticed the baffle had some cement crumbling under it so it's time to get in there and see whats going on.. I think I can remove the burners and baffle plate and mat out the front door. Yes, no?. And what would I use to cement the baffle back in place? Stove cement or the stuff that comes in a tube like glue?. Any advice on the removal of it all?
