It does seem kind of long to me, but I tend to keep my phone running pretty lean.
If I were you I'd probably look first at CameraLocker and AnyLockApp since they both alter the slider section of the lockscreen. Maybe there's a conflict there? Otherwise, I think the one-by-one option is unfortunately going to be the way to do it.
If you can pinpoint the reboots a bit, that would probably help...as in, do they happen when you get a text coming in, or maybe when you're using some specific app, etc. I used to have an issue that was somehow related to texts coming in just as I was doing something with my home button for instance.
One other thing: there is a known issue with the FolderEnhancer Fix toggle in Barrel conflicting with IntelliscreenX when turned ON. I know you don't have ISX but maybe it's conflicting with a different app...if you have that ON in Barrel, try turning it OFF for a bit.
Good luck!!
