Adam, I am willing to help. Where and how do I start?
Great! There are a couple of folks interested in working on this, so
we should be careful to avoid duplicating effort.
I would start by reading the JSON RFC (it's pretty short):
http://www.ietf.org/rfc/rfc4627.txt
Next, I would read Firefox's implementation:
http://mxr.mozilla.org/mozilla-central/source/js/src/json.cpp
For the precise JavaScript API, please see the ECMAScript 3.1 spec:
http://wiki.ecmascript.org/doku.php?id=es3.1:json_support
We want to match Firefox's (and IE's) behavior exactly. Then I would
look at our https://bugs.webkit.org/show_bug.cgi?id=20031 which has
some possibly useful code. If that code isn't useful, feel free to
throw it away.
Maciej recommends we implement this feature using our existing JSC
lexer and a bison grammar. I believe JSC already uses a bison grammar
for JavaScript, so it might be worth adapting that for JSON.

I already started with bison grammar just looking into how to write JS
Object to test the grammar.
