also I am not sure about titanium backup being restored on another phone. From what I have read you can, but you may have issues with some off the apps not being compatible and all settings not being restored.
I have only restored my backup with titanium backup when flashing to a new rom and it works great.
Sometimes I will use Astro File Manager to backup my apps. It will save all the apk files to your sd card so you can install them, without having to redownload.
Sorry if I am of no help
