I echo that answer. That is also the most 'correct' thing to say...
I would recommend using Cyanogenmod9 for newcomers, that is the ROM I am using as well (I have used others too). I think, because it has such a big development team behind it, it tends to have fewer problems (for me, none now), so it is quite stable. Others would probably contest this statement, which is totally cool too.
It is the most 'popular' ROM too, I believe.
My method of Rooting and upgrading Galaxy note to Cyanogenmod9 ROM:
I root the device using Chainfire's method of flashing a particular stock firmware with Odin, in that particular instance it won't increase your flash counter as well. I find this the easiest most worrisome free method of rooting the Note. Go halfway down page and read this paragraph "1.3. If you are not rooted yet: Flash a modified FACTORYFS". Link:

Reboot into Clockwork Mod Recovery, FIRST thing flash that Abyssnote Kernal, and simply choose reboot into recovery (not reboot into phone. Not a train smash if you do accidentally reboot phone, just reboot back into recovery and redo the step). This Abyssnote Kernal flashing step is the only extra step you need to perform due to using a Galaxy Note. Here's the
link. You can choose any of the 4 files.
THEN ONLY do you wipe data, cache, dalvik, and flash the the CM9 ROM file (or whichever ROM you want to use). Reboot phone, and voila! Have awesomeness bestowed upon thee!
Link for CM9.
Further
reading, though it contains different as outlined above (my method works, as do others, don't worry too much about differences). Just for your info
Hope you get it right
