Joomla website updates

We have a Joomla 1.5 website which requires the following updates: 1. When logged in as an editor on the front end of the website, the right menu overlaps some of the content. 2. We can only see the edit buttons on the front end when using Google Chrome. 3. Search box-needs to hold up to 50 characters (size should stay the same) 4. When the pdf, print, email icons are switched on the heading does not display correctly. 5. It has a sequence of images which change (Hotnewsflash from [login to view URL]) similar to [login to view URL], but within Firefox and Chrome, I can't click numbers 1,2,3,4. I can however click these numbers in Internet Explorer. 6. Joomla Featured Articles (from [login to view URL]) doesn't allow the Read More link to be inserted.
