Whoever told you that AP rates are only good Sun-Thur is misinformed. I have exclusively done Fridays and Saturdays on AP rates... in fact our SSR night in Sept was a Sat, and was $164. If you use your annual pass and login to disneyworld.com/passholder it will give you a super-special 1-800 number to call for AP rate ressies, and you don't even need the codes. You can also make the ressies there but the cancellation policy for internet bookings is fierce(45 day I think) so I usually check the internet then call. The phone booking cancellation is 5 days.
Also, w/ AP rates you can call weekly or even daily for an inventory check, as the CM told me that they release more rooms as it gets closer to checkin. You may also need to tell the CM on the phone to try to book 2 or 3 nights and then cancel the last 2, as sometimes they only release the rooms for 2-3+ night stays (I have had a CM do this for me before).
Hope that helps!
We have used our AP rated onthe weekends before to, but that was before the new reservations rates starting in '08. That could be where the change is if there is a change. Remember in '08 they charge different amounts on different days so they could have a no pass rate on Friday and Saturday. I hate that because those are the days we would always use our rates--on nights we did not want to use up all our points. Good luck and let us know what you find out.
