YSlow is very useful, providing you use a bit of common sense and don’t become too obsessed with your score. Some things (like CDNs) simply aren’t relevent for small sites. I actually tend to use this tool too: http://linuxbox.co.uk/website_performance_test.php it does pretty much the same as YSlow, but does a few extra things too (and invariably gives slightly different results)

[...] I’ve blogged before on YSlow, but here’s a word in case you’re not familiar with this ultra-useful tool for speeding up your web site. YSlow inspects a page you give it for compliance with Yahoo’s rules for front-end performance (my SitePoint article on the subject) and hints you how you can speed up your page, using a convenient action-oriented list. In addition to that there is a full list of the page components being inspected and also some other useful tools. [...]

hmm, and this is not good – YSLow complained that you use CSS expressions and here’s what I found:

.commentinfo {
height: 78px;
margin-left: 122px;
margin-top: -83px;
max-width: 450px;
width:expression(450 + “px”);
overflow: hidden
}

I guess you’re targeting IE that doesn’t support max-width. IF you find another way to do the same, it would be good, because these expressions are evaluated many times. This is your last concern though, your expression doesn’t access the DOM so it should be fast.

I’d say focus on 1-4 from the list above and see how it goes.
