It seems that he purposefully waited near the end of the statute of limitations (6 years) in order to file the lawsuit. I don't see this as a reason to question the validity of the lawsuit but, perhaps, strategy on his part to 1) see how the Winklevii did and 2) wait until FB's valuation was as high as possible before filing.

I think finding the emails on the second time around is suspect but defense lawyers will have a chance to review the evidence so it makes me think that DLA Piper did their due diligence to prove the veracity of these emails (otherwise they would know that it's likely to be thrown out before even coming to court).
