For the high idle, spray some carb cleaner around the intake gasket. If you hear the RPM increase then the gasket is leaking and needs to be replaced. Common problem.
The high idle sounds like a vacuum leak. It's likely around your intake manifold/carb area. I've seen a lot of vacuum leaks on old and dry rotted hoses to and from the carb. Maybe you'll luck out and find an unplugged hose. I'd start looking there for sure.
