The one thing I would caution you on as far as the Bay 13 method is concerned is that while you are attempting to wedge out half the dashboard top, you put a lot of stress on the black plastic in the vicinity of the defroster vents. I wound up with multiple cracks. Its not that much harder to simply remove the entire top and there is much less chance of damage. The only extra work is:

Disconnecting the battery.
Removing the glove box.
Unbolting the passenger airbag and disconnecting the red wiring plug.
Removing srews at the top lip of the glove box.
Removing a srew under the right speaker grille.
Removing the screws at the passenger window defroster vent (same as the drivers side)

Haynes manual has a pretty good write up. Make sure you disconnect the battery to avoid an airbag fault when you reconnect. Otherwise you will be taking it to the dealer to have the fault cleared.
