There are at least 4 ways (known to me) to deal with date/time crash:
1) Upgrading to a newer firmware
2) Setting time through Android Terminal app (root)
3) Installing Xposed GravityBox module and apply the fix (root)
4) Trick with the SIM card change (explained in another thread)
Which option you choose depends on whether you're root, and whether you feel up to the job. Going from newbie to advanced, I would choose in this direction: 4, 2, 1, 3.

There are many ways, but unless you're not rooted, app data won't be backed up (only APK files). In addition to Titanium Backup, you can also try My Backup Pro app, but I personaly make a complete nandroid backup with CWM, so I'm safe whatever happens.
If I helped you, clicking "Thank You" button will be enough.
