How do you want to "remove the application" without any type of application? In its simplest format, that is what the maintenance tool does. You can also call in "uninstall" if that is all you want it to do.

In regards to 4, that is possible with the Installer Framework, but I remember this to be an undocumented feature. I suggest to check the source code for that, specifically where the update location / repository is specified. That can be a folder on your local disk.

Rejecting to install into an existing directory is a default setting, I do not fully remember whether there is an option to disable that.
