i need follows views commets counter as http://vanillaforums.org/discussions and also i need search box on header + profile option on sidebar...[like this forum has]
The views/follows/comments counter you see here can be found in the Voting plugin. Some themes have similar functionality.
Or you can just create a theme or plugin yourself and echo $Discussion->CountViews; for views, echo $Discussion->CountBookmarks; for follows, since that's all the plugins or themes do.
The other things you mention you'd have to theme yourself, or find another theme that has them. If you're interested in tackling this yourself you can check out the Vanilla Wiki to get started.
