Urgent Help Required.

I know a lot of people will curse me for opening this thread but i really need help. I have searched and could not find my query resolved and i have no other choice left except to post here,

So my dad randomly gave me Galaxy Note (Indian version) today. I mean, this phone is 3 years old. Anyway, i have Sony Xperia L and Xperia SP as my daily drivers and flashing Roms, kernels is quite easy on them as i only require flashtool. I have never before used a samsung product. So, i do not have a clue on how to root it and flash CM/AOSP on it.
I searched quite a lot and came upon a rooting guides and Philz kernel but i have no idea what to do.
Any help would be appreciated, all i want to do is flash a custom Rom (CM 10.1, CM11)
Android 4.1.2 sucks on this beast.

Android: 4.1.2
Baseband: N7000DDLS6
Build No.: JZO54K.N7000DDLSC

UPDATE: So i flashed a .zip:- PhilZ-cwm6-XXLT9-ORA-5.11.2-signed and voila, i have root ;;)

Any help would be appreciated.

Thanks a lot :D

Ishaan
