Um, going back a bit, unless there's utterly no hope of doing it. loose Vista and get to Win7. That alone should make your life easier. OK, forward...
You didn't need to install SDK, etc. All you need is the Networking Pro GhettoRoot package and the PDA file. ADB is included in the package. If you've got SuperSU installed and your phone checks out with Root Checker, you're almost done. BusyBox is a collection of tools for the OS. You don't have to use them, but they are used by some other apps. BusyBox can be collected from Play Store, too. Install it. Then you're done.
Ignore the VZW "CD". When the window asking whether to run it or not shows up, do nothing but close the window. The contents are not your friend.
After that, some apps will ask for superuser permission. Titanium Backup, File Explorer, Root Checker, Clean Master all come to mind. If you see a request from an app you don't recognize, don't grant it SU! Please understand that rooting your phone removes a very important layer of protection from your phone. It's very easy to brick your phone directly, and there are people out there who are not your friend and want to ruin your day. If you're not good with that, maybe unrooting is in order?

The phone is rooted and running ND7. I'll give SafeStrap a try. What does this do, in the end, for opening the way to move to Lollipop?

No joy with SafeStrap. It looks as though it installed but... I used TI to do a reboot and didn't see the SafeStrap screen. I used TI to reboot to recovery and got the standard recovery screen, not the SafeStrap recovery screen.
Either this phone is haunted or otherwise in deep digital disaster because things like SafeStrap simply refuse to work. The app is there, of course, and it looks all wonderfully SafeStrap-like. I just won't create a TWRP recovery under SafeStrap. For that matter, TWRP also refuses to install directly.
The phone is definitely an SCH-I605, and it's definitely using ND7.
