Comboboxes Questions (linking and automatically updating)

I have the following workbook (attached) and it is in various states of disarray but I have two questions concerning it;

First, there are three ComboBoxes that need to be linked to each other in the form. When I say this, I mean that depending on the user, it will be easier for them to enter the property name, versus the property number or AFE number or visa versa. Is there an easy way to have it so that when any of the three boxes (WELL NAME OR YARD, PROPERTY NUMBER, or AFE NUMBER) are selected, the other two populate with the corresponding data?

Second, there is a tab to enter new property details (the tab is not finished) as additional wells go on line. I can get it to the point where the input data will appear on the bottom of the PROPERTY DATA sheet. However, how can I create a dynamic range that will include this new information in the corresponding ComboBoxes on the first sheet automatically? Or, if there is a better way then a dynamic range to accomplish this, I would love to hear that too.
