There aren't really steps, per se. You just start up a 6.0.6 instance pointed to your 6.0.5 database and it will update the database on it's own.
As far as the plugins go, just deploy them as-is (from the 6.0.5 sdk dir to the 6.0.6 deploy dir) and try them out. Unless you're doing EXT plugins, I'm willing to bet that most of them are going to work correctly and will not require any modification.
Otherwise, to recreate in 6.0.6 sdk, use the same steps that you did to create them in 6.0.5 to set up the directories and initial values. Copy your 6.0.5 changes to the new 6.0.6 directories, then do the deploy.
But again, you should be able to grab a 6.0.6 bundle, add your plugins to the deploy dir, then fire it up and it should all work just fine...
