What is good advice for someone moving into an apartment in NYC?

Ive lived on my own before in Orlando, FL but recently moved back to New York City (havent lived here since i was 16). Im now preparing to start what i hope is a position that leads to a career and looking at apartments to move out too.

What are some pointers, tips, suggestions you would give me for looking at different places, areas to live in, price ranges that i should be expecting, etc.

My job is down on the tip of Manhattan on Wall Street so im hoping to move somewhat close (currently live all the way in the Bronx).
