The first place to look is probably "The Implementation of Lua 5.0" (http://www.tecgraf.puc-rio.br/~lhf/ftp/doc/sblp2005.pdf).

Short paper, but very interesting.

The LPEG paper (http://www.inf.puc-rio.br/~roberto/docs/peg.pdf) is great, too.

The "History of Lua" paper written a few years ago for a presentation at HOPL is also great reading and gives good insight into why Lua is the way it is.
