Sure, but you only get a limited opportunity to modify times, assuming you plan to book your options as soon as you are eligible.
You choose your 3 attractions, and then MDE spits back 3 passes. If you are booking your passes the same time as the hordes are booking their passes, then the earliest time options will change on you the more you try to look at different attractions and times.
So, to some extent, within the above framework, you should choose rides you want to ride. I agree with your prebook #1. After that, it gets a bit murkier.
If I look now for MK for 11/8 the times I get:
iasw -2pm (on 11/10 same)
buzz 2:40 (same)
Dumbo 2pm (same)
HM 4:25pm (on 11/10 6pm)
teacups 2pm (same)
Philarmagic 2:40pm (on 11/10, 3:40pm)
PotC 2:10pm (on 11/10, 3:55pm)
Monsters 2:40p (same)
Aladdin 2pm (same)
Barnstormer 2:45pm (on 11/10 2pm)
Pooh 3:35pm (on 11/10, 4pm)
Speedway 2pm (same)'
LM 2:40pm (on 11/10, 2:50pm)
If MDE gave me ANY pass that is within 2hours of park opening, I didn't bother trying to toggle around too much. If you choose a lamer ride as 1 of your initial 3, you can, but you'll be making a bit of a trade-off when you are in the park. You might get a small advantage picking your 4th pass, but you will be sacrificing the ability to do a major ride while standbys are short. Hitting short standbys= potential re-ride using a LL pass.
Day of, my system was not that elaborate. I toggled a little between the best available and the next available worthwhile pass. As with G+, Dumbo, teacups, Philarmagic, and Monsters are always available, but the LL pass also doesn't impact your wait for those rides.
Kali does sell out on hot days, but it doesn't rank higher than the safari, IMO. I mean, for me, missing Kali is not much of a loss. I had no trouble getting it when I ranked it #4 after the safari on a hot day. Na'vi is a good #1, then I chose Safari and EE. If you do DIno as a standby before 11am, it will probably be walk-on.
Wow, today looks really slow at AK. At 1:30pm" FoP=35min, Na'vi =40, Safari =25, Dino/bug= 10, EE/Meet Pals =15, and TriceraTop Spin 5.
As a small aside, it bugs me that the name of the ride is TriceraTop Spin. The animal is spelled triceratops.
