1. The reply is correct so far. "Still in Active Process" seems positive but will need time.
2. There is no one stop service in Bangladesh Govt offices as long as i know. For PCC u will need to collect treasury challan of Tk. 250/- (for each person) from govt bank (Sonali bank better). Then u need to write an application on white paper addressing the DMP commissioner stating purpose for asking PCC with your PP details and address. Photocopy of your PP, Application, Challan all to be submitted to Ramna Police HQ at the so called "ONE WINDOW CELL" for PCC. they will send query to your local thana/ P.S . Then concerned officer from your thana will call u for tips or will come to ur house for the same. At the time of submission, they will give u a date of delivery. U can collect on the date if keep track with the thana.
