Just got done talking with a friend of mine who's a Ford master tech who's done a bunch of these. He says:

Pop the valve cover
Mark everything (chain, phaser, camshaft)
Throw vice grips on the camshaft so you've got something to hold the cam in place with when you unbolt the phaser from it (to keep it from drastically shifting, and to help you line it back up when you bolt the new phaser in place)
Shove the timing wedge in good
Pull bolt and remove the phaser
Transfer mark to new phaser, bolt it up, torque specs, yadda yadda
No need to pull lash adjusters, line the motor up, pull the cam, or anything, "simply as hell".

He says I "might" be able to move enough stuff around on the passenger side to get the valve cover off, but if not, then I'm going to have to discharge the AC.

I'll try to take some good pics while doing this and make a good DIY writeup.
