How much testing has Boeing done with lightning suppression on the 787? Can they accurately imitate a severe lightning strike? How have they acheived a confidence level to address this issue given the good history of Aluminum airliners in this area?

It will be addressed....simulated lightning strikes are part of the certification for a new aircraft Composite aircraft tend to have wire mesh embedded into the outermost layer of composite to create a Faraday Cage (just like a metal aircraft...)

Lots. Many years in the case of 787 specifically, more than 20 years for the general case of CFRP primary structure. Don't forget, the pointy bits (radome, nacelles, wingtips, empennage) get a disproportionate share of lightning damage and those have been CFRP (except the radome) for 15+ years.
