Do we need to use FP+ if its not suggested on the Touring Plan?

We found that on a less-crowded day (like Tues/Wed/Thurs) we used our Fastpasses in the morning and were able to easily get more for popular rides throughout the day. However, on Friday and Saturday, we used our morning Fastpasses and no more popular ones were available after that. In retrospect, on Fri/Sat we should have gotten popular FP for noon/afternoon when the lines are really long, and use the shorter standby lines in the morning.
Test Track was 25 min by 10am on Fri, but 50 min in the afternoon. By then my husband and daughter had no choice but to stand in line and wait (while I when in the single rider line and waited 10 min).
By 10:30am Saturday Toy Story Mania was 90 min wait.
Due to several FP timing/walking time messups at Magic Kingdom, I switched around the timing of my FP selections for Animal Kingdom to go in order of how I would walk around the park and it worked really well, much better than the days before at MK where my FP were all over the place. This took a few minutes of planning with the park map the night before, but saved us a lot of walking and time at the park. Not sure if you could do this last minute all the time, but it worked last Friday (first week of Oct).
