The wreck site alleged by the Google Maps guy is in the northeast quadrant of the lagoon (offshore from the northernmost or northeast corner).
Assuming Earhart knew what she was doing in attempting a water landing (an open issue in and of itself) she would have been coming in west-to-east - i.e., she would have traversed most of the length of the lagoon before stopping and sinking. This is in part supported by the fact the winds reported for the 24 hour period spanning the fatal flight leg were almost unanimously cited as being from the east.
I'm not sure how the copra plantation of the time was laid out. There was an older settlement on the island, which had been abandoned a year or two earlier but re-settled in 1937. Lambrecht's report mentions the largest structure visible was on the south side of the western end of the island. The bulk of the earlier settlement was more to the north.
Here are a couple of map images I culled from the 'Net, illustrating the Hull / Orona layout and the comparative sizes / orientations of Hull versus Gardner Islands.

As far as I've been able to tell, the alleged wreck site is roughly below (as in 'just south of', not 'underneath') the 'Best Channel for small boats' caption in the first image.
The most reasonable lagoon landing approach would have been from the west - over the western end of the island. This would have meant the approach would have passed over the established old settlement.
Earhart's last understandable radio transmission (in which she indicated she was shifting to the north-south search line) was logged at 0843 local time. My best guess is that there were 2 - 5 hours worth of fuel remaining at best. I reckon Hull would have been on the order of 2.5 - 3 hours' flight time from the Howland vicinity. This would put an arrival at Hull sometime on the order of 1115 to 1145 local time at the very earliest (if Earhart had headed straight there after the last clear transmission) and circa 1400 at the latest (based on my estimate of remaining fuel).
Lambrecht's arrival at Hull was probably around 1500 - 1530 local time, also from the west, and he reported people on the ground were clearly watching and waving at his plane.
