How to root phone?

Are the flash file on support already rooted?

I have downloaded the flash file for this phone:

BOOTLOADER

CODE

CSC

MODEM

but don't know how to use them.



Please advise what to do next. I already half-bricked this phone, spent many hours trying to revive it. Finally restored it by using Kies. It took about an hour :-(
