Sorry to hear you're having so many problems, but I suspect the manual un-install fixed whatever problem was preventing your privileged helper service from installing.

Each QRecall action is stored as an action file (.qraction) in the ~/Library/Preferences/QRecall/Actions folder inside your home folder. Each file is automatically named (e.g. important stuff-compact_0.qraction) in a way that should make it easy to identify what that action is.
If you have copies of your action files (say, in the archive that captures your home folder or still in your Trash), simply move/copy/restore them back to that folder and restart your system.
If you're a little bit geeky, you don't have to restart your whole system. The QRecall app and the background scheduler look at the Actions folder when they start up and after you make any changes to your actions. But if you manually alter the files in the Actions folder, you'll need to nudge QRecall into loading the Actions folder again. The quickest way to do that is to re-launch the QRecall app and the QRScheduler process. The later can be restarted using the Activity Monitor app; use the search field to find the QRScheduler process and tell it a "Quit" (a TERM signal, if you want to do this from the command line). It will immediately restart and reload the actions in the Actions folder.
