The blog title and tagline things can be set in the back office for each blog. Depending on what skin you have, your blog title and the title in the sidebar can be different by using either long title or short title, so again you might be able to do it in the back office. IF the top part and the sidebar are both showing the same bits you can edit _main.php to use title in one place and short title in the other, but I don't have a file handy to show as an example.
Your favicon code would go in _main.php somewhere up near the top before the closing </head> tag.
