Patsy Thompson has a couple of videos on how she spray bastes her quilts. I haven't tried it yet, but plan to with my next one. The gal at daystyledesigns.com has a couple of really good videos on how she sets up her regular sewing machine for quilting. She also has been doing a design a day project with 365 different free-motion motifs. Just Googling "free motion quilting" will give you a wealth of information.
If free motion is something you don't feel comfortable starting out with, you can stitch in the ditch and maybe do something like a star, heart or some other simple shape. I did stars on my first attempt and made a cardboard template and used a chalk pencile to draw around the edges. I have also made the motive out of freezer paper, ironed it onto the quilt and quilted around the design.
You will need either a darning or hopping foot for the free motion and a walking foot or machine with IDT for the stitch in ditch or quilting around designs.
