Ok it sounds like you are relatively well prepared! I usually tell people that 2 days is the bare minimum to see all of Disneyland Resort, with 3 days being recommended for first timers (4-5 is doable, but honestly not necessary and you’d get bored without other diversions to break it up in between). Add on VIP, DAS, and Genie+, and you will easily see and do everything you want to do. Don’t stress too much about the mechanics - you seem to have done your research, and you’ll figure it out.
One point I would like to make is that World of Color is my favorite nighttime show in any Disney park. Fantasmic is right up there and I know many people would put it first, but I wonder if there is a way you can work in both (or do WOC only if you’ve done Fantasmic at WDW?). Just my opinion.
You might find the thread below useful for answering this question. I’m linking my post comparing rides between DLR and WDW, but others in the thread answered the same question. As I said before, you should be able to ride and experience almost everything!
