IE uses alt, FF uses title, as do other browsers, which use what I can't remember off the top of my head. Probably opera and safari do though.
alt attributes (not tags) are alternative text for screen readers and non-visual browsers. It should be a short description of the image.
You should have alt attributes for all images and as stated, make them blank for presentational images. Keep the content short, ie "ACME logo" rather than "ACME's logo - an orange sun behind black bold text".
title attributes are used to supply additional information that is not essential, these work on almost every element (except base, basefont, head, html, meta, param, script, and title) but aren't required for any. Title attributes are supposed to render as tooltips.
Alt renders as a tooltip in IE Win, but that's a browser fault and no others do it.
An example of correct usage would be an image that links to a page:
<a href="/cliotrophy/" title="Statistics and information on the Renault Sport Clio Trophy"><img src="cliotrophy.jpg" alt="Clio Trophy"></a>
Meta robots - this tag is deprecated. If you want search engines to spider your site you don't need to add anything - a link from a site within the directory will do it. If you don't want them to, then look into the use of robots.txt
