I would add a good square up ruler for your quilting. I prefer the Martingale - That Patchwork Place one.
If you have any 'special needs' due to arthritis or something that makes the steps of quilting awkward, then there are more suggestions. I like my alto's QuiltCut 2 as I can cut more and more accurately. This is for when you have been quilting a while though.
When I started other quilters gave me my stash. All it took was going to a class at my LQS and joining local quilt groups/guilds.
Have fun.
