When removing hardware without uninstalling it properly a device will become ghosted or non-present.
These are easily found by setting an environment variable "devmgr_show_nonpresent_devices = 1" and showing them within device manager.

If I know that these devices will not be connected again, or can easily be reinstalled should I remove these?
Does windows still allocate I/O addresses for these devices and take up system resources?
