It is not supported to roll back an app to a previous version via the store at this time.
App developers can only ever have a single published version of an app, for any given version of the phone (so it is possible for 7.x to have an earlier version than 8.0 which in turn can be earlier than 8.1).
Unfortunately it is currently not possible to search for settings. Microsoft knows this list is getting out of hand and Joe Belfiore has hinted that the next version of Windows phone will deal with this issue.
In the meantime it is possible to pin some of the settings to the start screen using 3rd party apps or accessing them through the notification center....
