Sorry I don't think I'm really understanding your issue here. But it appears my first suggestion worked but now you have another problem with vertical alignment? This is just a wild shot in the dark because I'm not able to visualize what you are asking but I think maybe I understand so how about adding this to your other one:

#Navigation > ul > li > a:after
{
content:'\a0\a0\a0\25BC' no-repeat 50%;
font: bold 12px Arial, Helvetica, Sans-serif;
}
