Sounds like your Sychro's could be worn out, but your running 20w50 in your trans?

The higher idle is probably from the cold start valve. Kinda like a mini injector, but they normally kick off after 10 seconds. Have you checked for vacuum leaks?

My 85' kinda takes a while to warm up too, you could always get a colder thermostat so it opens up earlier.
