The nand is the internal flash memory of the xbox 360.
The 1bl is the initial boot loader of the 360.
Yes the fuse.txt is the fuse data that you previously wrote down.
360 FDT was an abbreviation to the 360 Flash Dump Tool referring to the thread we are in.

It is to my understanding you can extract your cpu data and kernel versions with in combination with the 1bl key and the cpu key. So basically I want to make sure I have everything needed to downgrade my kernel in hopes of a future exploit so that I can update for the newer games manufactured after "feb 20th."

In order for you to get these you will again need to run linux gain root access, ssh into the live cd, transfer and run some code in order for it to dump these things then transfer back to your pc. Correct me if I am wrong with anything but I am just learning as I am going.

So how we can downgrade (if knowing those fuseset keys) from kernel 5759 to 4532, if we don't have Hypervisor Vulnerability in kernel 5759?

Get a copy of kernel 4532, get an Infectus modchip (or modify an xD card reader), back up the contents of your NAND flash using the chip/reader, then use the flash dump tool on the 4532 dump to encrypt it with your key and set the version lock thingy to a suitably high value to allow it to work on an upgraded box with efuses popped. Flash this onto your NAND

You'll need to remove/doctor your hard disk, too, since otherwise it will try to upgrade you again.
