If you enter DCA at 9:30 you have until 10 for rope drop. In that time you can ride Soarin and or get a FP for Soaring to use later. You can also get WoC FPs and probably ride LM.
If you aren't near the front of the rope drop, the TSMM line will get very big when you arrive. So you can wait, or do Screaming first, then TSMM. You may also be able to get a CS FP around then, certainly after TSMM. TSMM will have upto a 45 minute wait for the rest of the day.
ToT has FP but probably will only have upto a 30 minute wait.
For just those four attraction it will be easy to ride them and easy to do each twice.
