the jailbreak = one tiny file
your other apps = un-install launcher, just fixup the link the store and replace old image?
unless you noob-sprayed junk all over (doesn't read like you did TBH) a couple of hours wiping seems like mucho effort.
still - if you want to - fair enough - your password is bypassed (IIRC) so even just "ENTER" will work to get access via usb0.
depending on the CONFIG in usbnet (that's /mnt/us/usbnet/etc/config ) different types of authentication may be used... read the README in the usbnetworking package. probably just want to add an authorized_keys file (with the right junk in it) for what you EXPECT to happen to happen.
Wiping the device is always an option. but it couldn't hurt to give the docs one more eye-over before making that decision.
