Portuguese applying for a China visa in Poland

Hi, I am a Portuguese living and working in Poland for 3 years (I have karta pobytu and PESEL). I will go to PRC as a tourist (L type).
Please correct me if I am wrong:
1) Where do I have to go to request the L type? Warsaw? Gdansk? (I live in Krakow)
2) How many times I need to go there?
3) How much will I pay for 1 entry? 150zl as I am inside the category "Other Countries"?
4) I don't have a recent passport photo as said on point 3. The picture for passports in Portugal are made on the same day using a photo+signature all-in-one machine on the office. Can I attach one of my recent photos or even take another one in 'passport-style'?
