Hello! bbPress comes with a bunch of built in support for a majority of standard WordPress themes. If bbPress isn’t working with your theme, it’s up to your theme author to decide if bbPress is something they want to support.

You shouldn’t need to do much more to get bbPress to look and work like the forums you linked to, once you get your theme sorted.
