You might want to start to look at tools like Visual Studio Team System or Red Gate SQL Source Control as a mechanism for implementing deployment processes that allow you to move things in an incremental manner.

If you just have to move the whole database every time, I'd go with backup and restore. It's probably the safest and most efficient. As far as collation errors, supply some documentation as to which collation should be used. That one is just a bit outside your control.
