How do you pronounce Roronoa's name? I've heard from varying sources that Roronoa's name is pronounced two different ways and I was wondering what is the correct way to say it. I have heard it pronounced 'Zoro' in the manga but my bilingual (Japanese and English) friend says that it is pronounced 'Zolo.' So what is the correct way to pronounce his name? 

What I'm trying to ask is, is his name Zoro or Zolo?

Also is Roronoa his first or last name?
The pronunciation of the hiragana character ろ is the correct way to pronounce the ro in Roronoa Zoro's name. This pronunciation lies somewhere in between the English pronunciations of Ro and Lo (though closer to Ro). You can find an audio file with the pronunciation on this page at guidetojapanese.org.

The canonical Roman spelling for his name is Roronoa Zoro, since this is the spelling used on his bounty poster. In the English dub, 4kids changed his name to Zolo for some reason. 



His first name is Zoro, and last name is Roronoa. The Japanese place their family name before their first name.
