The only ride I have ever seen run out of FP before noon is Radiator Springs. You should still be able to get FP for the things you want to ride in the afternoon. However, last week they opened Toy Story Midway FP, and I'm not sure what times those are looking like.
I believe @Caramerson was trying to be helpful in suggesting you create a personalized touring plan because it will make suggestions for what FP you need, based upon the exact time, date, crowd level, and rides you want to ride. The personalized touring plan option is very easy to use even without much knowledge of the park. Please remember we are all just passionate disney fans who have devoted hours of research to our vacations and are volunteering you help.
Rides with single rider: California Screamin', Goofy's Sky School, Grizzly River Run, Radiator Springs Racers, and Soarin'. If we ride Radiator Springs Racers without a fast pass, we always ride in the single rider line. California Screamin' is also another good option depending on the wait. Anytime we have been, it wasn't necessary as the wait was minimal. Ditto for Goofy's Sky School. I have never used the single rider line for Grizzly as we have always been able to secure a FP.
It is hard to say what I would plan for a late arrival day, because I don't know what attractions are on your must, maybe, and no lists. That being said, here is a start:
1) Radiator Springs FP
2) Ride Soarin'
3) Ride Goofy
4) Ride Radiator Springs w/ FP
5) Get Toy Story Midway FP
6) Ride California Screamin'
7) Ride Mickey's Fun Wheel stationary
8) Use Toy Story Midway FP
9) Get Grizzly River FP
10) Animation Academy and Turtle Talk (Depending on FP time)
11) Monsters Inc.
12) Ride Grizzly
I am also a rebel and deviate from my touring plan if I need to. Be realistic with your time, check wait times and you are going to have to review your FP times and fill in the blanks while on the go.
