1) You can buy prepaid SIM cards at millions of places such as book stores, gas stations, etc. The card of course comes with a number. You can always recharge the card buy calling customer service, online, or buy another recharge card.
2) Making international calls from your cell phone will be very expensive. So you have to get an IP card and dial the 800 number on the card with access code. If you have used IP cards in China then it works exactly the same way.
3) Make sure your cellphone can use 850MHz or 1900MHz bands.
It will be better if you have a world phone (quad band phone). Otherwise you will have to find out what company operates on which band and then get a SIM card you can use.
