Hello and welcome!
I can read through the excitement in your post. There is so much to learn to figure out as we progress through our quilting journey. One of the nicest threads is glide thread. I use it for piecing, bobbins and quilting so it is multi-use. You can purchase the smaller cones or the larger one depending on your likes. I am a one of each color girl so have a variety of choices.
Needles? Here you go.
