Student Exchange Programs

I am studying abroad in Arezzo, Italy at Uni. Siena @ Arezzo in Spring 2009. The semester runs February-June and I have a few questions:

1 - What are the normal temperatures February-Spring in Arezzo.
2 - What is there to do on a regular basis in the town?
3 - How long is the train ride to Florence?
4 - Is Arezzo an expensive place to live compared to the rest of Italia?
5 - Are there many English speakers in Arezzo?
6 - Any other information regarding daily life in Arezzo or information regarding exchange studying at the university would be helpful.

I will be studying through my university’s exchange program (Univ. of Oklahoma).
