Merged: Going crazy renewing Polish Passport in the UK

Sorry for another passport post, but the information online is contradictory.
I'm trying to renew a Polish passport in London.

-Do you need to make an appointment at the Embassy on Bouverie Street (is this the right place, the Consulate is at a different location) or can you turn up and wait (and hopefully get in)?

The website says you need an appointment, though getting an appointment seems difficult (they open on the 27th of each month, apparently).

-When you get there I assume you pick up the application form. Can you fill it out straight away and give it to the clerk, or do you have to go back in line (if you don't have an appointment) or do you need to come back (or make another appointment)?

-Do you need to bring your birth certificate?

-Searching online all the websites say the photo must have a light grey background, though the Embassy says a white background.

I'd greatly appreciate your help.
