So all the right things magically happen, rename files instead of doing klunky things involving killing buffers...

To rename multiple files in emacs, the most easy way is:

Alt+x dired to go to the directory.
Alt+x dired-toggle-read-only 【Ctrl+x Ctrl+q】.
Then, just edit the file names.
When done, wdired-finish-edit 【Ctrl+c Ctrl+c】 to commit the changes.
To abort, Alt+x wdired-abort-changes 【Ctrl+c Ctrl+k】.

You can use find replace when in edit mode. For example, Alt+x query-replace or Alt+x query-replace-regexp.
