Another website for free embroidery is
http://www.annthegran.com but it will really depend on what software you'll be getting with your machine how it will read the data and where it can come from. You'll need to know what format your machine reads, but that will be in your manual.
My machine has a bobbin sensor and the coats and clark makes it malfunction, but do spring for a box of speciality threads. The best deal I found was a box of 20 Madeira spools from Joanns.com
http://www.joann.com/joann/catalog.j...RODID=prd15360 It's $20 so the up front cost isn't bad unlike other big thread groupings, and you'll have all the colors you'd like to start out. With the $20 box you can add Sulky or other brands and see what your machine sews best with.
Also http://www.Allstitch.com has refill spools that are 1100 yards or some such for $2.45, with your first order they will send you a booklet of a whole bunch of different stabilizer samples so you can see what they are and which ones you'd like.
Hopefully your new machine will come with at least one font that way you can just put in the info you want on your quilt labels and voila!
