Anyone can sue anyone at any time for anything. The burden is then on the defendant to defend the case. As you noted, the NY case was dismissed without prejudice so the landlord is free to file in PA claiming whatever he wants. He is not bound by any amount claimed before. The only issues that remain are whether you are liable and the amount of damages all of which the landlord must prove.
Regarding the condition of the property, in PA, the burden is on the tenant claiming breach of warranty of habitability to escrow the rent pending a resolution. If the issues with the property did not constructively evict you, in that you could still occupy the premises, rent will not be waived.
I hope this helps, but do not hesitate to call or email on a free initial basis.
