First it unlocks the bits of your system that remain locked via nand. basically the system is being told to mount certain directories like /system as read only and not let you remount it as RW. This means your rooted but not completely because you can't re-mount these directories as RW under the android os. Doing this will allow you to remount /system as RW or read/write under the andriod os which will allow you modify things in the /system/app directory letting you clean up bloatware you don't want without having to boot into recovery to do so. (Among other things... that's just a good example of what this gives you.)

The second key thing it does is flash a custom recovery image, basically the same one you load now via toast's recovery-windows.bat process, that you can boot into directly from the HBOOT menu. This means that when you want to flash a new ROM or do a nandroid backup, you don't have to go find a computer with the android sdk and toast's evo-recovery.zip extracted on it to run recovery-windows.bat in order to do so. you can dl a new rom directly to your devices sd card and go to town or boot directly into recovery and run your nandroid backup without needing a computer and the previously mentioned tool set to do so. This was also prevented by the nand locking that this process overcomes.

in short, part 1 gave you root but only about 1/2 of it. You could run apps that require su/root but you can't modify key parts of the system that you should have access to as root. Part 2 completes the root process giving you 100% control of your system without having to jump through hoops to achieve it.

And as I understand it you WILL need to do it to flash a custom ROM written for full root (could be wrong on that)
