Go to the lessons at the shop where you purchased it ASAP!
I don't have the 11000, but the 6600. It's the 3rd Janome and I've attended the lessons for each machine. Just get in the driver's seat and use your machine as much as you can before you go to the lessons, and to get the most out of them. You'll find there's things that they'll teach you that are easier/simpler than you have been doing them ... and discover new tricks that you hadn't already. And with the experience you've had already, you'll have better questions and be more attentive to the lessons.
ENJOY! your new machine!
