The blocks in the sidebar(s) on the left and/or right can be managed through the blocks administration interface (administer >> blocks). You can
- turn blocks on or off.
- configure individual blocks so that users may choose whether to turn them on or off
- change their location to left or right, or move them up or down.
- configure individual blocks to show on specific pages or areas of the site.
- create custom blocks (see the "sample block).
The menu administration interface (adminster >> modules) will allow you to customize the main navigation menu (the one with your username as a title). You can create new menu times, rearrange existing ones, or even create whole new menus.
Navigation links in the header can be modified in the themes administration interface (administer >> themes, select configure) by editing the primary and secondary links (some HTML required). Some themes use a different theme generation method, so you may need to configure these links by configuring the theme itself. Other themes may not provide navigation links in the header at all.
