Asking questions in multiple threads makes it harder to help you and for you to find our answers so try to keep one topic in one thread and give us time to help.
Be as specific as you can when you ask questions and be sure to answer our questions when we respond so we can help you better.
It sounds like you do not have any experience with either crochet or knitting. They both produce a fabric, but they look different from each other and the pattern stitch can can change the appearance. Knitting is done with two needles and crochet is done with one hook.
I don't understand your second question. What do you mean by "don't answer"?
A good yarn to start with is Caron Simply Soft or maybe Red Heart SOFT.
We can't suggest patterns till we know what you want to do or your experience.
