I don't own that particular machine but wanted to chime in. When I purchased my most recent computerized machine with 400+ stitches, what I did was cut doubled pieces of muslin into 8.5"x11" pieces, loaded the machine with dark-colored thread, and stitched out each and every stitch pattern. (I know they are all printed in your manual, but I like to see them actually stitched on fabric.) Then I took a Sharpie marker and wrote the stitch number above each row of stitching, put each muslin piece into a clear page protector, and put them all into a binder. That way it's a quick reference for me as to what stitches I have available.
Other than that, I would say just read the manual... very carefully. Sometimes we miss a little item here and there and it causes us grief (smile).
Good luck with your new machine.
