Use a coin or spudger to rotate the battery-locking screw 90 degrees clockwise.
-
-
-
Remove the three evenly-spaced Phillips screws from along the rear wall of the battery compartment.
-
-
-
Lift up on L-shaped memory cover, slide it to the right, and lift it out of the computer.

Remove the following 3 screws:
-
One 11 mm Phillips #00 in the middle of the case.

Two 14.5 mm Phillips #00.

Remove the following 3 screws from the rear wall of the battery compartment:

One 4 mm Phillips #00 on the right side.
-
-
-
Remove the two 6 mm Phillips #00 screws from either side of the right wall of the battery compartment (not the ones closest to the battery connector).
-

Remove the four 3 mm indicated Phillips #00 screws from the front wall of the battery compartment. When working from the left, remove the 2nd, 4th, 7th and 9th screw.

Starting near the display and working around to the front of the computer, pry up on the upper case. It is held with clips on the right above the optical drive. These will release with some firm lifting pressure.
-
Be careful when prying up the upper case. It's very easy to slice open a fingertip and thus provide the blood sacrifice the Mac gods sometimes require of those who insist on doing their own repairs.
-
-
-
While holding up the upper case (from the bottom or the top), use a spudger to pry up the orange trackpad and keyboard cable from its connector.

Grasp the white plastic tab attached to the hard drive and pull it to the left, removing the hard drive from the computer.

Two 3 mm Phillips near the right speaker.

Using a spudger, gently pry up the white plastic slot and slide the metal c-channel to the right and away from the display.

-
One 3 mm Phillips on the right side of the fan.
-
One 6 mm Phillips on the left side of the fan.
-
Four 9 mm Phillips securing the heat sink to the lower case.
-
-

These are excellent instructions. To replace just the keyboard/top case will take about 15 minutes.
To replace the bottom case will take about two hours.
In addition to the coin, phillips head screwdriver and spudger, I recommend working on a large towel, and having some scotch tape.
Working on the towel will save you time and aggravation if a screw gets away from you - it won't go very far.
Print out the instructions from the PDF document. As you remove the screws, us a piece of tape to grab the screws, fold over part of the tape to keep them secure, and then tape the screws to the step in the disassembly process.
When you get to the point of reassembly, your parts will be right there at the step as you need them.
Thanks to the people at iFixIt for their excellent guides, and their excellent support and response time to questions/posts! Awesome job!
