I think everyone else has pretty much covered it, but I'd also like to mention sororcula's pet project a delicious page tagging every fic posted to numb3rs_news. She's only finished a few months, but it's an easy way to find things!

AND! You'll come across it at the numb3rs_awards but irena_adler's Watson 'verse. It's long and plotty and has a couple of OC's but it's AMAZING. *nods* Very first piece of fic I read in the Numb3rs world was in it. The master list is here!
