PMP recertification - Have earned my PDUs

I completed my PMP in 2011 and my cycle dates are between 30/8/2011 and 29/8/2014.

Today I have collected the required 60 PDUs for recertification .

I have following queries before I submit the recertification :

  • The recertification fee for PMI non members is $150 . Is there any benefit if I renew my membership and make the payments . I mean if anyone can let me know what is the fee PMI member needs to pay for certification ?
  • If I recertify now , will my cycle start from today or from the date when I complete my current cycle ?
  • If I dont recertify now , how long are the current PDUs valid for ?

If anyone has answers to these , thanks to answer at the earliest
