I have two versions of Safari. Version 5.1.1 (7534.51.22) is in my applications folder. Version 5.1 (6534.50) is in my applications/internet folder. I am pretty sure that i should delete 5.1. Correct? Is there any cleanup to do after that?
For future reference, don't move applications that came with the system to new folders. It will mess up the updating process (as you've obviously witnessed).
