Earring/necklace newbie- follow-up questions

[amante-di-fiore.livejournal.com]

Thanks to all those who posted wonderful responses to my previous post.  I have one more quick question.

I am interested in using simple chain and charms for necklaces- do I just use little rings to attach or is there a better product?

For earrings, I'm interested in charms as well- I know I need the earring hooks, but other than that I don't know how to attach them - do I need pins or rings?  The simpler the better.

Thanks- sorry for the follow-up, I'm just trying to get started.
