British passport query

Which is the quickest and most feasible way of applying for passport as I have seen people are applying online or by post or using check and send service.

There is no 'quick' way. The processing time will be the same whether you apply online or through the Post Office check and send service. You will also need to attend an interview before the passport can be issued.
Although the guidelines are for processing within 6 weeks this doesn't allow for an interview and in addition this is the busiest season of the year for passport applications, so be prepared for a delay.

Thank you.

The website is a bit confusing. Am I correct that I only need to send:
1. Citizenship certificate
2. Two identical photographs

No birth certificates or any other supporting document, right?

You were born outside the UK
You have a certificate of naturalisation or registration
Send both:
your naturalisation or registration certificate
the passport you used to come into the UK or the foreign passport you’re included on

I suggest you read through the guidance booklet (the link found on the online application) or if you're still unclear, use to Post Office Check & Send Service.
