I'm glad you're figuring it out Caley. It's really too bad you don't live close to a Baby Lock dealer. You could get lessons there.
You might try this table.
I found it on Amazon, and because it folds up, and is super sturdy, I really like it. It has a steel frame, so it's heavy. But that is also what makes it good for holding up that heavy Jazz.

Also, for helping you sew over/past those big lumps, try this jean a ma jig. It is what I use when making my own jeans.
It is sold at almost any fabric / sewing / notions store:

And I totally agree with you and MKC.... You can't really trust all those reviews....
