Your questions are probably answered by the Upgrade page. I don't know what you man by "loose regions" even if you actually meant "lose regions". If you are worried about losing region free operation, all the region free techniques are still available for 4.3U.
The one thing you want to make sure to do is just to upgrade everything before you update the Wii. That will ensure the update won't delete anything you currently have on there.
