Pokemon FireRed Questions

I have a few questions about where to find some power up items
<BR>1) Where do you find Magnet? I think on magnemites/magnetons, but not sure
<BR>2) Twisted spoon? I think on kadabra, but also not sure
<BR>3) Scope Lens?
<BR>4) Dragon Fang? Maybe Dratini/dragonair, need confirm
<BR>
<BR>And please check out my team!
