Answer 1

Make it appear like a table cell:

#vert-menu > li > a {
    padding: 0 35px 0 5px;
    display: table-cell;
    height: 30px;
    line-height: 15px;
    vertical-align: middle;
    color: #FFF;
    text-decoration: none;
    outline: none;
}

Answer 3

I think the following modification does what you want:

#vert-menu > li > a {
    padding: 0 35px 0 5px;
    display: block;
    height: 30px;
    line-height: 15px;
    vertical-align:middle;
    color: #FFF;
    text-decoration:none;
    text-align: center;
}

I added text-align:center .

But personally I prefer the left aligned version.
