So, are you saying that, after this new law, we can get only NIP? Are you sure?

How to get PESEL: info request

Hi all,
I live in Wroclaw and I'm trying to understand the right procedure to get the PESEL.

In a previous POST #% in this TOPIC, I found this guide (thanks to user JollyRomek)

polishforums.com/law/pesel-citizen-working-company-krakow-73239/#msg1464032

Ok, most of this seems clear...except:

-- Applications forms, Statement specifying your arrival in Poland, Statement indicating that your understand your rights and duties of registration : what documents are these? Where can I find them?

-- "zaswiadczenie o zarejestrowanie pobytu obywatela unii europejskiej" is the "blue card"?

-- when I will go to town hall (for the second "step"), do I really need my landlord? Can I simply show document of my lease?

Can someone "help"me?
Thank you
