If I understand correctly, you need to use frames. You can create new
frames from the menu (Menu-Bar->File->New Frame) or "C-x 5 2". Then
you can split those frames into multiple windows. To move between
frames you use (Menu-Bar->Buffers->Frames-><frame to switch to>).
There is likely a way to move between frames with the keyboard (or
create the capability) but I don't know what it is.

It looks like the command other-frame moves to the next frame. It is
bound to "Control-x 5 o" which is pretty cumbersome. You can bind it
to another key or key-combination in your .emacs file, e.g.:

; use F8 key to switch to the next frame
(global-set-key (kbd "<f8>") 'other-frame)

There are two commands which seem to  save and restore buffer/window-
configurations in a frame that might suffice for what you want:

window-configuration-to-register  (bound to Control-x r w)  to save
it

and

jump-to-register (bound to Control-x r j)

So if you get a particular buffer/window-configuration set up you can
save it with c-x r w  (you have to then type a number for a specific
register e.g. 1, when prompted)
Then you can set up another buffer/window-configuration and save that
with c-x r w (giving a different register number when prompted)

Then you restore them at any time with c-x r j (and register number
desired at the prompt)

You can simplify the keystroke combinations and typing by adding
something like this to your .emacs file:

(defun SaveWinConfigToRegister1 ()
"save window configuration to register 1"
  (interactive)
  (window-configuration-to-register 1)
)

(defun RestoreRegister1 ()
"restore configuration from register 1"
  (interactive)
  (jump-to-register 1)
)

(defun SaveWinConfigToRegister2 ()
"save window configuration to register 2"
  (interactive)
  (window-configuration-to-register 2)
)

(defun RestoreRegister2 ()
"restore configuration from register 2"
  (interactive)
  (jump-to-register 2)
)


(defun SaveWinConfigToRegister3 ()
"save window configuration to register 3"
  (interactive)
  (window-configuration-to-register 3)
)

(defun RestoreRegister3 ()
"restore configuration from register 3"
  (interactive)
  (jump-to-register 3)
)

; <CTRL-F1> to save window configuation to register 1
(global-set-key (kbd "<C-f1>") 'SaveWinConfigToRegister1)
; <ALT-F1> to restore window configuration saved in register 1
(global-set-key (kbd "<M-f1>") 'RestoreRegister1)
; <CTRL-F1> to save window configuation to register 2
(global-set-key (kbd "<C-f2>") 'SaveWinConfigToRegister2)
; <ALT-F1> to restore window configuration saved in register 2
(global-set-key (kbd "<M-f2>") 'RestoreRegister2)
(global-set-key (kbd "<C-f3>") 'SaveWinConfigToRegister3)
(global-set-key (kbd "<M-f3>") 'RestoreRegister3)

There are two commands which seem to  save and restore buffer/window-

Now THIS does much more of what I expect!

I'm going to read up on it for a little while and see if I can't
improve the usability of it some more. It definitely now looks like
I can mimic vim's tabbing and splitting behavior.

Thank you!

Non-vulcans usually do it with `C-x b'. Some humans even use a mode like
`ido-mode'.

If I understand you correctly, you want something like elscreen, which
maintains a set of window configurations and (I think) has tabs that
let you switch between them.  See the Emacs Wiki for this and other
similar packages.
