Best way to install is obviously from the Xposed Repository.
Best way to make sure root functions are operating is to tick the "Close Opened Apps" checkbox and then the "Use Root Method" checkbox - it should then prompt for root access. If it's already ticked, untick it - in your root app delete the HTC Car Xposed! entry, return to the settings app and re-tick the "Use Root Method" box.
As for dependency on Sense launcher, it shouldn't have any - but I haven't tested it.
