Bank accounts, currency exchange, and financial advice for an American in Hong Kong?

Moving to Hong Kong for two years, and seeking advice on keeping the finances in order. I've been hired by a company in Hong Kong and will be there for a minimum of two years. I will be paid exclusively in Hong Kong Dollars. However, I have some small recurring bills and such that will need to be paid in USD. This seems like a pretty typical temporary-expat situation, and I wonder how other people have approached it. In essence, I'm looking for advice on and experience with HK banks and credit cards, and transferring money from HKD to USD at regular intervals without getting screwed on the exchange. Any and all experience with expat finances in HK is appreciated. Status: US citizen of the Brooklyn type, no debt except rapidly diminishing student loans, one US brick-and-mortar bank checking account, one ING Electric Orange checking account, couple of investment accounts through Vanguard, couple of US credit cards that rook me for 3% when I use them abroad.
