Answer 1

Yes, that phone will work. What you need is a phone that is quad band GSM.

Look at the link you posted and the 'Band: frequency' bit.
See there are 4 frequencies? That's what you need. 3 of them work in Europe, 1 works in the US.

Basically you need a GSM network so either Cingular or T-Mobile, not Sprint or Verizon.
