I have been to DW a number of time with my kids (DD 3 and DS 7), most recently this June when we stayed at the Poly. The best advice I can give you is to listen to what they want to do, but then get them to pick the three (or 5) things they really want to see or do and then make those a priority. It is, of course, impossible, to do everything. There were many rides that we got fast passes for which went unused, parades we wanted to see that we missed, PS that were made that we had to cancel because someone was napping, etc. I have been to DW at least 10 times and just saw Spectromagic for the first time this last trip. The important thing to remind them is the Disney World will always be there it is also fun to have some things left unexplored that you can look forward to doing on another trip. When my DS was bummed that we did not get a chance to do TOT, I reminded him of all the other new things we did on this trip, like RNR. Try to keep a somewhat relaxed pace and enjoy the things that you do try rather than squeeze in as much as possible. If they love the pool, then by all means, hang out there a bunch. Try to resist the temptation to go commando on them. I think you are right to stay "kid focused". You are going at a great time of year and the lines should be short. That will help you do a bunch of things without a lot of lines. Have I rambled on enough here?
Anyway, have a wonderful trip.
