Sash, oiling a serger is even more important than oiling a sewing machine because the serger does so many more stitches per minute. On mine, there are just two oiling spots, both underneath the machine, where the round rods slide back and forth through thingies with holes (two places where parts rub together). It's important to brush out or vacuum out lint before oiling.
I used my serger a couple of times to make a quilt. Personally don't care for so much extra thread in the seam; makes the seams bulkier. I have seen intricate quilts done on a serger using strip piecing, but it takes expertise.
The real value of a serger to me (assuming the serger has differential feed, which most do) is its ability to sew knits without stretching them out of shape. So much better than a sewing machine for this! However, since I rarely use knits in quilting, it's not that useful to me for quilting.
