Your questions are good. Thanks for asking.
> If you've got two of some species on the ark, but full populations on the periphery of the flood, how are two more going to make any significant difference?
Since it's impossible to know the full extent of the flood, and what animal species and populations were affected, it's impossible to determine how allegedly "full" the populations were on the periphery. All we know is that God was preserving species, which would have been an environmentally responsible strategy.
> So that's a delay of however long it takes for olive trees to grow big enough to have branches with leaves.
Olive trees are very difficult to kill, and the resprout quickly and easily. We need not have a fully grown tree and foliation to fulfill what the verse is talking about. Even a small new leaf would give an indication that the lower elevations (olive trees don't grow in high elevations) have drained sufficiently for vegetation to sprout. It shows Noah that the floodwaters are almost gone and that recovery has begun.
> if it's a local flood
By "local" flood I'm not talking about the kind of event that's happening in Iowa and Nebraska right now. I'm talking more like what Glenn Morton theorizes happened about 5.5 million yrs ago (not that I'm claiming this was the biblical flood). Morton suggests that the Mediterranean was not a sea at all, but that the Straight of Gibraltar, which was once a solid dam, was broken and water from the Atlantic Ocean inundated the entire continental region. Such a deluge would have affect close to a million square miles of land, and the rains from such an event would be lengthy and torrential.
Another geological example is when the waters from the Mediterranean found a pathway to the Black Sea area (happened in about 5500 BC). About 60,000 square miles of the region became part of the sea very quickly.
I'm talking this kind of inundation, not a "local" flood like when the Mississippi or Missouri Rivers overflows their banks. It's possible, given this scenario, that having two more of some species could have helped the species survive.
Since we know so little about the date and extent of the flood, it's difficult to gauge such things with any confidence.
