If you want to keep the autocomplete functionality intact you can use a bit of jQuery to remove Chrome's styling. I wrote a short post about it here: http://www.benjaminmiles.com/2010/11/22/fixing-google-chromes-yellow-autocomplete-styles-with-jquery/
if (navigator.userAgent.toLowerCase().indexOf("chrome") >= 0) {
$(window).load(function(){
$('input:-webkit-autofill').each(function(){
var text = $(this).val();
var name = $(this).attr('name');
$(this).after(this.outerHTML).remove();
$('input[name=' + name + ']').val(text);
});
});}
