Bangkok

Since I am moving to Bangkok to work from July, I would like to know the minimum expenses I need to live in BKK per month, including housing, transportation, food, entertainment, etc. Is $150/ month enough to rent an apartment in BKK? I am also looking for a place near skytrain or mrt to live in BKK, if you know, pls let me know. My office is on Silom road. Thank you.

During the peak hours, evening and morning, how long would it take to drive from Bangkok to Amphawa?

What are the best places in Bangkok/Pattaya to shop and bargain? I have been to Pratunam, Chatuchak, MBK, Siam Paragon and Silom in Bangkok, and Walking Street and Mike Shopping Centre in Pattaya. Please do a ranking based on the best place to the worst place... Do comment on your decision if you can... :)
