Korean BBQ home cooking help

So as a big fan of Korean BBQ, I wanted to try preparing it at home. The only issue I have is find the dduk bo ssam (rice paper) and making the chadolbaegi (brisket) dipping sauce/soy sauce looking dipping sauce. I usually dont have a problem finding the meat, because I usually find it at the Super H Mart in Diamond Bar, but just the rice paper and the dipping sauce is the hard part. I live in Diamond Bar, but would like to know where I can find the rice paper at and how to do the dipping sauce. Please help???
