How do I find out what version I'm using?
If my version is too old, how do I upgrade?

Okay, so after reading that, I added the following to my .emacs file:

;; shell-prompt-pattern stuff
(require 'tramp)

(add-to-list 'tramp-default-proxies-alist
             '(nil "\\`root\\'" "/ssh:%h:"))
(add-to-list 'tramp-default-proxies-alist
             '((regexp-quote (system-name)) nil nil))

I can now successful open things like /sudo::/etc/ to sudo open local 
files, and I can open remote files under my username with, eg, 
/address@hidden:~/, but if I try and open /sudo:thehost: I still get:

ad-Orig-error: Cannot connect to different host `thehost' with `su' 
connection method

I don't mind adding something like the above, I just don't want to have 
to add stuff *and* add ssh config in my .ssh file for each host I want 
to connect to. The holy grail for me is to be able to use any of the 
following:

/address@hidden:~/
/sudo:thehost:/
/sudo:address@hidden:/
