Next thing to buy, a heaping tackle box full of patience. Learn the basics and don't stray from them. You may get frustrated but if you stick with it it makes all the difference.
WF-6-F, If I remember right a 5x or 6x leader and pick a matching tippet. 6wt is a good one to learn on, too light a rod is hard to learn on, I know. I started with a 4wt and about broke it over my kneee I don't know how many times. I got a 7wt and learned quickly and was able to go to a smaller wt much easier.
I have used monofilament as a leader in the past and I have found I broke my leaders on fish way too much. I started going a lot lighter on my leader and this stopped but when I matched my tippet to my leader I never broke another leader.
And I will second the odea of a good 18" of tippet/line for the leader. It is a pain to tie on new tippets all the time if you start too short and lose a dozen in the bushes behind you on in your hat.
I love taking my kids fishing, now if I could just manage to fish at the same time.
