That's why I "prefer" to ask you (or from this list) rather than dig up
some strange, unknown, blog post off the web. However, I also realize
that many people have much busier lives than I do so it's important that
I do as much on my own and through my own research that I can.

I'm used to looking at panels like below where I have access to A,
CNAME, MX... when I didn't have that with this domain I was thinking
WTF? Then it dawned on me that it was the first domain I had registered
without having hosting services automatically attached. At Dreamhost I
had all records, at GoDaddy I had all records, at HostGator, at
Hurricane, etc..

Ahhh?? (I want to elaborate but not sure how to put it into words). I
think I get what you're saying here though.

Since this is my very first DNS lab, I just want it to work but, I
totally understand what you're talking about and as you may recall I
even mentioned the brilliance associated with your own nameserver
distribution some time ago; it's ok if you don't remember but I do.

EC2 allows me to pick from various locations where my servers will spin
up at as in SF, NY, FL, (other countries), etc. which I believe would
meet the necessary requirements of different geo locations as well as
power grids/circuits. I may be limited in selection since I'm on the
"freebie" tier but I believe I have a choice of about four different
locations to choose from.

I'm guessing the webserver and master nameserver can be at the same
place since if the webserver goes down the nameservers are irrelevent
anyway (remind you of anything)? =)

So I would need two other locations for the slaves ns2 and ns3.

Yeah, screenshots are good for that. One could write an entire page on
trying to describe a chicken or simply send a photo of a chicken; you
pick. =)
