I Finally got the LA1 ROM installed on my Note along with the CF Root Kernel LA1 provided in the Chanfire thread.

And many thanks to those including those who provided links to Stock ROM LA1 on various threads including ketan.
I installed from the CWM app and selected CF Root kernel when asked to do so..
Voila...Hit Flash Normally Button... and Ding ,Ding Ding...
Changes Noticed so far :
1. The Touchscreen is now more awesome than ever before. Remarkable improvement in touch sensitivity .
2. Lockscreen now Shows the line - 'Swipe to Unlock'
3. Some new apps from Samsung ( Samsung Music Hub )
4. Notifications Window is zipping fast.
5. new Option in Keyboard settings to Use keyboard with a Single Hand
6. Voice Command (VLingo) much better and responsive.
7. New Torch Widget
Testing more rt nw...
After that However , Out of some curiosity , I changed my CSC to Open Europe through *#272* method. Although the CSC changed from Korea to Open Europe (India -INU was not there )..I think it doesnt matters as much.
Before this I was on KL3 Stock ROM for Indian version along with Zengbrush + CF root + CWM . And did the following:
1. Made a ROM backup through CWM
2. Did a Titanium Backup for only user Apps.
