The J Reference Card is updated to 6.02 and with color. It is at http://www.jsoftware.com/jwiki/HenryRich?action=AttachFile&do=get&target=JRefCardv602lette r_20071003.pdf
Ric Sherlock did the work of formatting this version. I think it's a big improvement. If you print on both sides of the paper you will do well to print on heavy stock so the back of the page doesn't show through to the front.
