Hi Brandi,
I think you'll enjoy your Brother machine. It's great for a beginner and is easy to use.
For quilting, you'll mainly use the 1/4" quilting foot. That foot will ensure that your seam allowance is the same for each seam you sew. The walking foot is useful after you've put your top together when you are ready to attach the top, the batting and the backing. I've never seen a walking foot that requires you to drop your feed dogs to use it, so you'll want to check with your sewing machine manual. Most of the feet for your machine will snap on; it's a very easy way to change feet.
I would suggest, in addition to watching videos online and any videos that may have come with the machine, that you find someone locally who will run through the basics of threading the machine, winding a bobbin and attaching the feet. It shouldn't take more than 15-30 minutes to go over that. Someone here on the board who is in your area might even volunteer.
You may want to post on the Main board so your post gets seen by more people.
Hope this helps!
Lynda
