Some customization questions?

I'm kind of stuck with a couple of things on a site i'm setting up. If anyones got some pointer they'd be greatly appreciated.

So here's the list of stuff I'm trying to do but have stumbled on.


- Remove Elgg branding from top bar and 'powered by elgg'

- Translate 'settings' button in topbar

- Translate sidebar items on settings page.

- Change the color of the 'Login' button

- Change the color of the border around the search field

- Set default visibility (for discussions and groups) to 'Logged in users only'

- Translate Report this button
