Sounds like you've got some fun stuff planned! How long are you staying at Aulani, or in Hawaii altogether?
One thing I really, really recommend for first timers to Hawaii is to plan plenty of time to just "be". Hawaii is a special, special place, and I think folks miss it if they're too busy. I have not done the Dole Plantation as many consider it "touristy", but a quick stop for a Dole Whip and a look at their shops could be fun. I can't imagine spending too much time there. I have also heard both good and bad about Germaine's. I think the biggest negative for you is that Germaine's is a good distance from Aulani. Have you thought of doing Paradise Cove which is almost next door to Aulani, to save yourself a lot of time on the road? I've heard that Germaine's is in an industrial area and can be hard to find. I have done luau on Maui, so I had no need to attend one on Oahu. Others can give you input here.
The Gypsy App is pretty sweet, just be certain to entirely download it BEFORE heading out. We really enjoyed our drive over to North Shore and then down the Pali Highway. Very pretty.
Pearl Harbor is a place that has to be experienced. It was awe-inspiring and beyond sobering. Truly a must see. Trip Adisor's Oahu forum has some excellent ongoing posts by "Dusty" that outline Pearl Harbor that I found super helpful. For instance, you cannot take your purse, backpack, etc., with you to the USS Arizona. There's a little booth off to the right of the entrance to the park area where you can pay a small fee and leave your bag. You can take your phone ONLY if it's turned off or silent and ONLY if you're using it for a camera only. Please allow plenty of time for the drive, especially if you are heading in at rush hour which can be beastly. Keep in mind that if you're heading FROM Aulani into the Honolulu area, so are MANY, many locals heading into work. And vice versa on the end-of-work-day time frames.
There is a Big Target and Costco just one or 2 exits back toward Honolulu from Aulani where you can pick up all sorts of goodies for your stay if you like. It's really only about 5 minutes away.
Do NOT miss the Starlit Hui show at Aulani. Make certain to ask when you arrive so you won't miss it as it's only a couple of days a week. Go early to grab a grass mat to throw on the lawn for your "seats" and check out the handcrafts around the perimeter. It's a fabulous show.
There is truly outstanding live Hawaiian music performed in both lounges at Aulani nightly, many are Na Hoku award winners, which is kind of like the Hawaiian music Grammys. Superb!
We loved AMA AMA most for breakfast and lunch. The views are gorgeous and we found the portions large enough to share in most cases.
Do you have kids? Also if you love spas and don't mind a splurge, the Laniwai Spa is fabulous!
