I don't really know what causes the problem with Gary's phone call.. but maybe it stems from incompabilities, just to make sure that this isn't the case - have you installed any other mod or similarly things before or after you installed CE, TheBloodyRose? If yes, you'll want to re-install Bloodlines and the CE mod because it's incompatible to almost everything except skin changes and very, very, VERY minor tweaks.
Since that's all I know, you'll just have to wait for the experts to help you if my advice didn't do the job. Sorry. :/
As for Kelben: As far as I know, the issue with the phone getting back to it's place isn't anything that can be fixed. I've had that with my Vanilla version, too, and still have it with CE - nothing to be done about it, I'm afraid, so I guess you'll just have to ignore that fact.
