Service [Q] help to flash Honamifity for Xperia P

Im a newbie to the phone flashing world...
i liked the Honamifity ROM for my SONY Xperia P. As i told earlier that im a newbie, i needed help in rooting nd flashing my phone.
First of all i needed a list of all the softwares that i will have to download according to my firmware version 6.2.A.1.100. I wanted to know if i'll have to put a new Kernel into my phone. The details of my phone are as follows:

Model No: LT22i ( Xperia P)
Firware Version: 6.2.A.1.100
Kernel: 3.0.8+
Android Version: JB 4.1.2

Thank You in advance!
