General labels in List view vs specific gps data

Question

I am hoping someone can explain how one can have specific gps info and useful labels at the same time. My iphone will tag photos that I take on Kauai, and many of those photos will be in places that iphoto cannot name with any greater detail than "Kauai". This results in having photos with a "Kauai" place name for photos taken very far apart. It's unclear to me whether all iphone-tagged photos automatically show up somewhere in the Places List View, but I do know that many of my auto-tagged photos will be labeled "Kauai", which is not specific enough. Does iphoto still know the difference between a westside photo and an eastside photo even if both have "kauai" as their label?
To remedy this, I could go into an event and label all the photos in that event "Hanalei", based on Places I've listed manually, but if I do this, all photos for that event are shown at a single location, losing the specific GPS info for each individual photo. I thought if I created a place like "Hanalei" and gave it a wide circle, that iphoto would automatically put any photos that were tagged within that circle into the Hanalei list. And perhaps it does that while maintaining it's "Kauai" label.
Can a photo come up under many manually defined circles, while still maintaining it's specific GPS location?

Answer 1

It seems that about 5% of the pics from my iphone create GPS locations that are off.....some by a mile...some by alot more than that. So, yes, using the photo's info window....i drag the pin to correct those. I wasn't aware that everytime i did this i was creating new manual placename. If that's true, that will result in alot of places called "Kauai".
I'm asking many of these questions because in the Places List View, I have so many duplicate names in columns 3 and 4 that it renders the whole interface nearly worthless. I'm surprised there aren't tons of people with this problem.
