Getting a list of site users in Sharepoint 2010

Question

I'm developing an application on top of Sharepoint Foundation 2010. I'm wondering if it's possible to get all defined users of a certain Sharepoint site? By this I mean getting their IDs (or GUIDs, however they're represented) as well as their human friendly names. So I need any special rights to do this?
