Great! I don't mind PMing, but I often forget to check for those. If I don't answer, post in the forum and I should see that.
For the backing fabric, the easiest route is to purchase an extra-wide fabric made especially for backings so you don't have any seams. There are good places online to order this width of backing in a variety of colors and subdued patterns; post separately to ask for some places to check out. Or, you could go to
http://www.joannfabrics.com and order Kona muslin in the width you need (probably 108" at $8.99/yd). There is another thread here on the forum that contains a 50% off coupon for JoAnn's and you could use that when you order. With this width, you just order enough yardage for the length of the quilt (adding at least 12 inches for safety). Kona muslin is one of only a very few muslin fabrics I would actually use for a quilt backing, as most muslins are IMO not good enough for that use.
Edit: Here is a link to the thread about Joann's coupon codes:

I just used the 50% off one and it worked fine.
