You are in for a lot of quilting fun! I've had my Sweet 16 for a couple years now and just can't get enough of time using it.
My personal advice is to watch all the HQ videos that apply to what you want to do with your machine. And don't, simply don't miss Jamie Wallen's videos. His videos helped me more than the HQ videos--although HQ has added many new videos since I purchased my machine.
Happy Quilting!
