In the first post, there is a Quick Root Guide.
For you old firmware, the second (DooMLoRD's zergRush exploit) method might still work.
That is very easy and will not increase the flash counter.

Good luck.

P.S.: As your firmware is very old, you really should consider to flash a newer ROM. Maybe you should create a complete system backup in CWM recovery (=> nandroid backup) after rooting. Then flash a new ROM. And if it does not work or you don't like it, you can restore the backup again to go back to your current system.
As soon as you are rooted, you can use Mobile Odin app to flash other stock firmware versions and/or custom kernels without increasing the flash counter.

Does this erase any memory in my mobile?

Rooting wont erase anything, but flashing a new firmware/rom will. Won't erase your pictures, music etc but will delete your apps, contacts and messages. You can always make a backup of your contacts and messages using apps like SMS backup+
Once your rooted, you can make a backup of your apps with titanium backup.
This is a very common doubt.Search the forums for more information.
