Forget about Dole Plantation. It is mostly a store.
Pearl Harbor, including transport, will take you a 4-5 hours, and would be best to do as part of a round-the-island trip. That way travel time is partitioned amongst many other sites as well.
How long do you want to snorkel?
Should be fit enough - got 2 marathons a few days before
From what I've read, it's best to get to the beach area early as it fills up and some other comments mentioned the water getting choppier in the afternoon.
Time wise, depends on how many fish are there to see.
Never understood why a lot of tourist attraction close early. It can be light until say 10pm yet by 5pm, that's it.
