Okay, so I downloaded the Drunken Paladin today, and while I'm playing it I'm seeing things in odd places, and the Drunken Paladin seems to be using my game's tilesets, Since I changed my tilesets so much it looks really bad, do I have my tilesets in the wrong place or something? Was I supposed to keep the default RTP tilesets in the RMVX folder and put my edited tilesets in my game's graphics folder? :\ I feel like such an idiot...

Yeah, you only need to import the tilesets from within RM. You should be able to change them back by simply reinstalling the RTP though.
