Indian living in Poland applying for Chinese VISA

I am an Indian Passport Holder but have my Karta Pobytu until 2013 September and plan to visit China for 2 weeks for holidays. I will have my return tickets and also hotel booking - however will not have any invitation letter from relatives there. Is that fine. What will be my VISA fees??

My husband is also joining me in Poland soon and will have a valid Schengan VISA- can he also apply for VISA from here as he will be in Poland starting September and we plan to visit China in December.

Thanks a lot,
