Hi,
It should basically be Skilled Worker since PEI PNP eligibility is either Skilled worker or Skilled Trades or CEC. Since you are not into trades and CEC it should be FSWP which is Skilled. I too have chosen Skilled Worker.
You can refer this link for more information which actually list the categories for PEI PNP.

Coming to your next question, yes, the photograph has to be scanned and sent along with the rest of the applications and forms, etc. You only courier the Bank Overdraft physically to Office of Immigration, PEI.
Wish you Good Luck!
