The "keyboard locking screw" is a transparent plastic screw located between F5 and F6 function keys.

To put back the AirPort card with the clasp (wire brace), make sure the card is pushed against by the wire, not clamped over. The latter situation indicates that the card is not seated deeply enough.

I had a hard time getting the Airport card seated properly when reconstructing. If the wire brace doesn't snap back in easily, then try reseating the card. Don't force it.

Honestly, this is a lot easier than it looks. The key is take your time and don't force anything. Use tweezers to disconnect cables from logic board. Also, use a mini-head screwdriver like for glasses to pry the case open and go slowly.

very gently magnetizing my small philips screwdriver was a HUGE help when putting all the tiny screws back into place... all said and done, there will be a lot of teeny screws to be taken out and put back. To magnetize the screwdriver, I just rubbed it several times in one direction (similar to sharpening a knife) across a strong refrigerator magnet... you only want it just strong enough to hold a screw, but not so magnetized that it corrupts your new hard drive!

When replacing the RAM shield, make sure to pull the antenna cable through the tiny slot in the upper right, or else you'll have to unscrew it all over again.
