Reimport data from unistalled apps

My question ist twofold and I am really looking forward to any help.

 

I have a package that has dozens of custom objects with references to standard objects like opportunities and Chatter feeds. I need to uninstall and reinstall (with a slightly changed schema) this app. 

 

I read that the data zip that is created after uninstalling contains all data as csv that can be reimport with the dataloader and other appexchange tools (Informatica, Skyvva,...)

 

Question 1: What happens to references to existing standard objects and Chatter feeds related to the uninstalled custom objects?

 

Question 2: Can you suggest a simple and cheap way to import automatically all those interelated objects from the csvs in the zip?

 

Thanks in advance.
