I have heard of a spray you can get called "Quilt Glide" that is supposed to help the fabric move freely over your machine/table surface. My friend Kelly said it works great. She sells it on her website (http://www.jukeboxquilts.com/store/machineQuilting/quiltGlide.html) - maybe you could find it other places too.
I use latex gloves (medical supply kind), but boy do my hands get sweaty! I might try those rubber fingers from the office supply place....
