Once i have downloaded the rom
I have to unlock bootloader, root the device and then flash 4.2.2 on the device. Is it right ?
And when i will flash custom roms on device it will replace the stock 4.2.2 ?

yes, it will overwrite.
the battery life is more related to Kernel than ROM; so to get good battery life it would be better to flash a good kernel...

I have seen different tutorials for updating galaxy nexus to 4.2.2. It says something like this

"In order to do the update your device needs to be running build JOP40D"
But when i saw my settings in the mobile, my built number appears to be
JRO03C.I9250JPLH2

Now whats the point here .. ?
how to update the device in this situation
