Here's what I have found:
A 2002 article mentioning both:
"Gravity"
www.guardian.co.uk...
Article mentioning that NASA is working with theorist Ning Li. 2002
"Anti-Gravity Engines and Laser Weaponry"
robocat.users.btopenworld.com...
This site may be of some significance to you. It claims to host a load of documents from both Ning Li and Podkletnov:
"American AntiGravity"
www.americanantigravity.com...
A 2002 article mentioning Podkletnov:
"Anti-gravity research on the rise"
www.newscientist.com...
Google on Eugene Podkletnov:
www.google.com...
Nothing mentioned on the current status of Podkletnov, that I can quickly find.
