One of the best things about Whole Brain Teaching is that you can integrate as much of it as you want into your instruction. The mantra is "it's a long year, keep a big back pocket" You DON'T want to introduce everything at once.
You DO want to monitor, just as you normally would as the awesome teacher you are, and see that if something isn't working, you simple move on to the next step. WBT is scaffolded and tiered, so you don't have to THINK too hard about moving on to "something else that works better" It's just how the program is set up!
That said, make sure to check out the First Steps section. Also, go to the blogs people have started (check out the "WBT is looking for Bloggers!" part of the forum) There are tons of resources on interns and others' blogs about how to integrate, and what it looks like, etc.
And most of all, keep asking questions! The WBT community is here for ya!
