Living in Lisbon

Hi Everyone, I'm new to this forum, and I was just wondering if anyone here knows any info on the cost of living in Lisbon?

Price of an apartment: 1 bedroom w/ kitchen, bathroom, living room. per month

Price of food: For 1 adult for a month

Price of transportation: For a month (I would like to travel around the Lisbon Metro area, and possibly Porto, and Braga)

I plan on moving to Lisbon, in October of this year (2011) To play football, I know there are currently 3 teams in Lisbon in the Portuguese Liga (Sporting,Benifica,and Belenesse)

I'm 18, and I would love to find a local football club just to kick the ball around, and if I'm any good hopefully get spotted by the teams in the Portuguese Liga.

I'm also interested in going surfing and going to beach parties, so what area in Lisbon would you suggest would be the best (centralized) area to get to a lot of places in a short period of time? I have read that Rossio is a good place?

I would also be interested in getting a part time job, that would require little hours, but with a reasonable pay. Say 500 euros a month. What jobs could I get? (maybe an english tutor? or photography, or a writer at a English newspaper? Any idea's?

I would also like to learn Portuguese, do you know how much it would cost for lessons? Or possibly free ones?

Any advice, or help you can give me would be greatly appreciated, as I'm having a difficult time finding accurate info on the net.

Thank you in advance!
