As for the leak, if you can get a picture of this hose then we will be able to confirm it is a coolant hose. However, if you have not purchased it yet, I would ask that they fix the leak prior to purchasing it.
As for changing each of these components, they do not need to be replace after 100,000 but instead when there is an issue that requires their replacement.
The word "need" to replace them is what I suspect is misleading. They may fail and require replacement after 100,000 miles but they are not required to be replaced just because it reaches 100,000 miles.
Let us know what other questions you have. Thanks
