Can I delete unnecessary apps? (Most inside)

So from the downgrade to 3.55OFW from 4.31 OFW and then to 4.30.2 Rebug. I have a few questions about unnecessary apps.

1. Do I still need Toggle QA from 3.55 or can I delete it? (Would just like to delete it so if anyone uses the PS3 they don't screw anything up)

2. Do I need Condor Updater or can I delete it? (Would just like to delete it so if anyone uses the PS3 they don't screw anything up)

3. Do I need Rebug Toolbox or can I delete it? (Would just like to delete it so if anyone uses the PS3 they don't screw anything up)

EDIT: Just to clarify they're all installed so I just want to delete them (uninstall i think so it doesnt show up above MultiMan)
