To be honest, I hate the import tool. I would hand punch it personally.
That being said, I know the import tool will accept:
Telephone directory
Agent Assignment
Agent Group Assignment
Path Assignment
Multiline set assignment
Singleline set assignment
Trunk Group assignment
Trunk Assignment.
Probably more.
Use the import at your own risk, you will probably find yourself correcting tons of stuff and taking as much time as handpunching anyway.
