Triscuit,
it is different, but not rocket science. Most of the 8.5 tools are there, they have just been shuffled around. Simple tasks are very easy to get used to - the more complex ones harder. It isn't like moving from Sonar 7 to 8, but the ergonomics do make sense.
Only start new projects. You'll love the ProChannel effects before long if you have producer. And if you don't have the optical comp, get it as soon as you can. And yea, the smart tool is usually smart.
Give yourself time, and spend the time to set up the interface the way that makes sense to you.
