I have android version 2.3.4 and build number 4.0.2.A.0.62
My bootloader is locked.
The only method i Know is to downgrade to 4.0.2.A.0.42 or upgrade to ICS and then root it.
is there any other method?
If i flash my rom to downgrade/upgrade then will I loose all my data/setings etc?
If so then how to backup everything and restore it?

Remember rooting may void your warranty and you are doing it at your own risk
There are 2 methods, one you know and the other is changing kernels.
Download the rom 4.0.2.a.0.42 and just flash it's kernel and then root using any method
Then again flash back the kernel from 0.62 and you will have a rooted 0.62
You know how to flashk kernels and firmwares ?
To flash firmwares, see How to Downgrade part and to see how to flash just the kernel, see How to root 4.0.4

I it recommended to upgrade to ics from gingerbread?
Will the phone will be as smooth on ics as it was on gingerbread?
I mainly use it for gaming.
(I know it is not the best phone for gaming but i hate big phones )

if it's only for gaming it might NOT be a wise idea as there are many games that aren't working with ICS (Sony's ICS)
