Default DO i need to downgrade ?

i have a Xperia Arc runing official ICS 4.1.B.0.587 firmware, its already rooted, got CWM working.However, the phone is pretty much laggy, so i need to change my ROM, im looking forward to install this ROM : [ROM][Arc/ArcS/Pro][2.3.7] Gin2KitKat v3.2.0 [OTA]

my question is do i need to downgrade from .587 to a GB official ROM ? because ROM Firmware Required: 4.0.2.A.0.xx and im runing 4.1.B.0.587 if yes do i need to re-root my device and istall CWM again ??

if no.is there anyway to install GB via CWM without loosing root access ?

It's better to downgrade first before flashing that ROM.

You have to change kernels since both are of different Android versions.

That ROM should come pre rooted, there is no need to root again.
