I can't point you to a tutorial, but perhaps you're using overly large chain. Try a finer chain, and hang more than one bead per link (at least 2). That usually works for me. As for your wire showing, try using finer wire, and really good quality round nose pliers, as they tend to have smaller tips to make a smaller loop. Whew--holy run-on-sentence!
I hope that helps a little.
