You didn't mention who you were traveling with but there is something that can help you maximize your day ~ SINGLE RIDER LINES!!
If you are on your own, or if everyone in your party is over 7, you can ride the RSR and Screamin' using the Single Rider Lines with minimal wait. My kids and I LOVE the single rider line at the Racers for a few reasons: 1) we can ride multiple times in an hour and 2) we usually end up racing each other vs. riding in the same vehicle ... always good for bragging rites!
We start the day at rope drop or before with Extra Magic Hours and head to Paradise Pier to ride Toy Story once (or twice) and then back to Carsland where we ride the racers a few times using the single rider line. Then we experience the rest of Carsland. On our way out we stop by the RSR FP machines and check the return times. Usually at this point we can grab a set with an evening return time

which allows us to ride at our favorite time of day and with each other.
We then head back towards the Pier and ride a few of the rides that never have much wait ~ single rider for Screamin, Mickey's Death Wheel, Swings, Sky School, Golden Zephyr, Mermaid and by now our 2 hour window has passed and we can get another FP so we head down and get one for Soarin. Usually lunch time at this point so grab a bite to eat and then based on return times, hit Soarin with our FP and then GRR or get a FP for GRR. The challenge trail is fun and a good way to use up some time if you need to before FP return windows open.
We then head to the other side of the park and do the attractions there, usually grabbing a FP for TOT though it isn't always needed. We enjoy the Monsters Inc. ride, Turtle Talk with Crush in the Animation Building and the Aladdin show if the showtimes work with your day.
A&E FPs for M&G are stand alone as are those for WOC so they will not keep you from having other FPs if you decide you want to meet the princesses or use a FP for WOC.
BugsLand is definitely worth a walk through, just for the execution and amazing details ~ its a great way to get from TOT back to Carsland even if you don't plan on doing any of the rides.
Hope you have a GREAT trip!
