As above, read the FAQ, then if you have further questions, most people here would be happy to oblige.
As for posting your toon. Copy the following, but replace the colored text with the information it tells you to:
[link=
your toon's Armory link here]
your toon's name here[/link]
It should come out looking like this:

Conversely you could just copy and past your Armory, but it takes up more room and isn't as "neat" looking ;)
