I don't think it matters if you are only freezing apps, rather than removing them, as you can always thaw them.
If you have Titanium Backup, then I guess you are rooted? Do you have a custom recovery? If so, boot in to recovery and make a full backup of your phone, then go back in to your phone and freeze any that you want (maybe one at a time) and, if any do cause you a problem and you can't thaw them, you can always restore your backup.
You are talking about the Lucid, aren't you? I ask, as you haven't listed it in your devices and want to be sure
