It's a very popular question, so don't feel weird asking.
Check out Dr.X's sticky on "How to Cut" which will provide you will a tutorial on how to create a diet to lose weight.

NEVER cut your calories that low, it would just be rediculous.
Doing arm curls and bench everyday wont be to much good either, your muscles need time to heal, and rest. That's the only way they will recover and eventually get bigger. I also believe you are going a little overkill on the cardio as well.
Once you've read over Dr.X's sticky put a diet together and then post it up for us to take a look at, everyone here would be more than happy to help you as long as your willing to put in the effort
