Short question: Does the speaker really remember all MPs

[Jeneral2885]

names by heart and where they are from?

1. Interesting question - he's certainly supposed to!

I expect that in practice he probably recognizes the troublemakers the most readily!

It would be interesting to see whether part of the Speaker's brain gets bigger, with all the names and associations that he has to remember, like London taxi drivers do as a result of 'the knowledge'.
