How to customize Mac desktop?

[TrillyandTruly]

I was browsing through the "April 2011 Desktops" forum, and I was wondering how people are customizing their backgrounds. I'm new here, so I'm still learning. For example, I've seen people with custom icons on their docks, and on their desktop, it shows the weather and time and all that. How can I get those? Thanks, and sorry for the noob question.
