2 Things:
1. Is there a way to change the lock screen?
2. I did not wipe coming from liberty, the only issue i'm experiencing is that google search won't update and is saying the package was incorrectly signed, is there a work around or should I wipe? If I do wipe, would titanium backups of my apps from liberty work?
1. No unless you install an app that does it.
2. I would imagine that the issue is wiping. And your backups of the user apps should work. The system apps, not so much.
