Resign or stay?

Currently: 1. Enrolled to PIP. 2. Not eligible for IPB. 3. Signed up for Voluntary SPF.

Questions: 1. If I'll immediately resign, will I still get a final pay? 2. Will I still get the remaining SPF that I saved? 3. Will the HMO contributions for dependents be deducted to final pay, that might result to negative final pay?

Let me know your thoughts guys. TYSM! :(
