You want:

rails new whatevertheappsname -d mysql

Generation of scaffolds/etc. is like this:

rails generate scaffold blah name:string content:text ... rails generate migration add_field_to_blah ...

Hope that helps!

Also, might be worth checking out: http://railscasts.com/. The last few episodes have been dedicated to switching to Rails 3 and are very helpful.

Definitely, Ryan Bates has a winner in Railscasts. One of the few things I look forward to on Monday mornings.
