Ok you can edit the spacing here. There are 2 sets one for the header and the other for where the text is below the logo. You may only need to adjust one area but I gave you both below for reference:
#s5_pos_custom_1_inner {
padding-bottom: 85px;
padding-top: 75px;
}
template.css lin 612
#s5_header_area2 {
background: #fbfafa none repeat scroll 0 0;
padding-bottom: 40px;
padding-top: 40px;
}
template.css line 606
