What I need is to

Answer 1

This is possible with CSS3 selectors and formulas:

.something a:nth-last-child(-n+3) { ... }

You could also try using jQuery (example) or adding a specific class to the last three elements in your server-side code (it does not require JavaScript to be enabled in browsers and also works on older browsers that do not support CSS3).
