Don't ever be hesitant to ask a question. Sometimes those of us who have been quilting for a while forget to mention the little details to new quilters. You are so lucky to have this board. I am a self taught quilter who started 30 years ago when there was no internet.
Hand quilting thread is usually used only for hand quilting. Because it is glazed it will show more if using it for piecing and it might make your seams heavier. I always quilt with an off white hand quilting thread. Others use colors. I like my stitching to rather disappear so you only see the texture. (Does that make sense? Don't know how to explain it.)
If you have other questions, just ask away.
