Welcome aboard. I find I also use a long measuring tape, 120 inches here, a lot since I buy a lot of material from thrift stores etc. Plus it helps to get a rough idea of the size of your tops if your kind of careless as I am about individual block size.
Good thread is also a help especially if you have a fussy sewing machine.
Thin long flower headed pins are pretty useful and not too expensive and you can write on the flower heads to number rows or do directions. Fons & Porter did some very expensive pins with R, L, U, D and really you could write all that on the flower pins heads.
I like topstitching machine needles for quilting.
Can't think of too much else that hasn't already been mentioned.
