No, you dont need root or unlock bootloader.

I did that 3 days ago, my xz runs better now, you need flashtool,drivers and the rom you want to flash

Yes it is, just flash an ICS ftf

EDIT,
Sorry my mistake, now I am at my PC I can see you have a V.
In which case rooting is easy..just unlock you rbootloader and flash an insecure kernel.

You can use any Rom that is based on a stock firmware and kernel.
Make sure you have cwm recovery to flash Rom

Not unless someone manages to find an exploit to unlock it.

i heard you need to be on stock based firmware to install the recovery,
but you can flash on other roms and manually flash the kernel or something like that
im not too sure,

BL is already unlockable, one unlocked u lose all DRM, there is no need for exploit.
Root was needed just to push the recovery to the stock kernel.
And CM uses a completely different kernel than the stock and the only way to flash it by unlocked BL

Exactly. I'm not sure of the chances that non-unlockable devices will become unlockable. If I said any amount if time I'd be making it up :/
One of the devs said that Sony bootloaders are locked up tight though...

Because not everyone can unlock their phone and doing it voids warranty, but just rooting does not
