newbie

I've recently just started making icons, wallpapers, etc. ... the only photo editing program I have is Fireworks, which my brother has told me is basically the same as Photoshop, but he won't show me how to use it, so my stuff is pretty primitive compared to what I want to accomplish as I get better.

ONE Does anyone use Fireworks?
TWO If you do, can you teach me how to use it (better) and tell me what all it offers?
THREE Do you ever do tutorials for Fireworks, or can I take the tutorials for Photoshop and use it on Fireworks?

Thank you for any help you may offer :)
