Hi and welcome!! I very rarely crochet with balls of yarn. The ONLY time I roll my yarn into balls is if I use something that comes in a "hank" versus the skein or if I am using something like Landscapes that comes in a "ball" but it isn't really a ball LOL. So, I don't think it is necessary to roll your yarn.
The homespun yarn, I have never worked with. I have worked with yarns that were hard to see the stitches with however, it is usually just the first row. After that, it all seemed really easy to me. Good Luck!
