Can you be more specific? What do you realy want to do? Posting a vague question like this, I'm affraid no one can help you. There is a good place to hang out www.8052.com if you want to learn how to work with 8051 MCU. However, if you post the same vague question like this overthere or sort of gimme code, they won't help you. They're professional coders, thus they don't like gimme type questions.
Regards,
T.L

Learning is by doing. You definitely need an assembler. Try ASM51.exe (from metalink, try googling for yourself )

Buy yourself the chip, and ask your friends who knows.

learning assembly langauge for 8051 is very easy
lot of tutorials available in the forum
or otherwise use keil microvision to start coding with c

Use 8051IDE, code is limited for the demo version but enough for you to start learning.
