For quilt-as-you-go, you'll want a relatively thin batting for your first time -- nothing that says "high loft." Other folks here can better advise on which kind.
I honestly don't use much besides scissors, needles (machine and hand), straight pins, safety pins, thread, a plain old #2 pencil, a 24" steel ruler, and occasionally a carpenter's L. For handwork, such as finishing a binding, I like a pair of small scissors for snipping thread -- I can leave them on top of my work and they won't stab me in the foot if they fall off the table! LOL
Hope you find some fabric at a good price and enjoy making your quilt!
