Since this issue of pasted text having the style of the original document when you don't want it, and it possibly affecting subsequent behaviour, happens not only in OO but also in other apps, I usually swap the setting for normal paste, and Paste with Current Style, as the latter is what I normally want, either doing it through the Keyboard preference pane, or in an app with its own shortcut preferences like Nisus Writer, through that.
