I have seen some posts here - but I wanted to find the following:

Quickest / Cheapest solution from JFK to Jersey City and the return as well. I know EWR would be a much easier commute, however i am coming from BOS and I need a direct flight.

I am not familiar with the PATH system and would not even know where to begin...

If I take a taxi to World Trade Center (which i believe is the best option) what PATH options would I need to arrange?

Thank you for ANY help you can offer!
