Well personally I would add a dot command that allowed you to teleport to and from the noobie grounds from any major city. IE: using the predefined boundaries of a city's guard warning zone, if your character is within those cords allows you to teleport to the noobie grounds. Once you are whisked to the noobie grounds it saves via a cprop what your old xyz was when you were whisked away and when you leave through the teleporter it just send you to your old XYZ which would of been any town of your choosing. Sounds more complicated than it actually is I know.
Next, I would re-enable that map that allows you to choose which city you wish to start in when making a new character.
As for a .guide, I don't know, what does a new player need to know, perhaps gems to moongate locations, a brief run down of religions?, in game class info (ie skills and stats required to join the classes in your baseclass group)? Here is a big one and something that I think needs to be there, a list of available dot commands and what they do, we have a bunch of dot commands and I am certain a few new players don't know about them, hell I would even add vendor speech commands to a menu. Think of it as the Codex of Wisdom but for Pangaea, I toyed around with editing the cliloc files to make the Tome of Wisdom more Pangaea oriented instead of just UO but gave up on it cause it would of probably just been for my amusement. See this is the kind of crap I think about when I am bored macroing
