New to Note 4 - Boot Loader / Root Confusion

I just picked up my Note 4 and have not even turned it on yet.
I have a few questions after reading various multi-page threads that i am unclear on.

I was looking at the threads and see that ChainFire is what to use to root.
http://forum.xda-developers.com/note...-root-t2897428
It states that Stock Recovery is installed, does this mean that I can use that recovery to flash TWRP or will i have to use ODIN for that?
What version of ODIN needs to be used?

Is there any version of Root that does not trip KNOX?

I am confused about the different boot loaders / Broadbands (basebands?).
How do I find out what boot loader / Broadband i am on?

I am reading a lot of reports that 5.x is giving very poor battery life. Is that the Case Still?

Thanks for any help Ya'll can give.

My Lenovo K3 Note is stuck in the boot loader.

I rooted my K3 using Kingroot V4.5.0.722 and everything was fine but I then replaced it with SuperSU and that worked. Once everything was done with SuperSU it said to reboot and the reboot has me on the boot loader or 2hours so I removed the battery and tried to leave it off then reboot and it didn't work. I tried to factory reset using the factory mode and even that didn't work. Please help.

Re locking boot loader.

Hello! I just got a nexus 6 a few days ago, and I love this phone! However, I just read on here that relocking your bootloader is a bad idea? Well, I rooted my device and installed PAC ROM on it, then reflashed a stock image back to my nexus and relocked the bootloader, my phone is fine, no bootloops and no issues, does this pose a problem with OTA updates? Thanks! I really need to know because i would NOT wanna brick this thing! Thanks!

help please. stuck in boot loader screen

What's up guys. I recently bought a 2014 moto x us cellular. Turns out it was stuck asking for the last Google sign in. I decided to flash back to stock using fastboot. Used motofastboot and entered all the commands correctly, but now it says failed to boot or boot up failed after flashing the m Motorola screen for a split second. It also says failed to validate system image in pink. I tried both the 5.0 and 5.1 factory firmware. Fastboot didn't say any errors. I can't get rsd to see it. Any suggestions?
