Is PSN global or do I have to worry about inconveniences/incompatibility?

I don't live in the States, I'm actually in Lebanon, but I'm getting faster internet soon (1Mbps download - yeah I know it sucks but around here it's like really fast) and I'd really like to play online with a headset - my question is, if I have an account for this country, can I play online? I know I can't access the store and stuff but in-game online play should suffice. Also, is 1Mbps download (not sure about the upload but it should be decent, less than the download though) enough to play it lag-free?

Random (possibly noob-ish) question: If I don a headset with mic, I can still hear the game sound right? How about if I just hook up a USB mic to the PS3 and forget about the headphones all together, would the game sound + other players' voices be on the TV speakers?

Thanks in advance.

Should be fine. You should be able to connect to the online stores too. I have a PSN account for Ireland, USA, UK and Japan.havokmaster
