Hello,
1. You can change the width here:
.s5_logo {
cursor: pointer;
margin: 0 auto 6px;
text-align: center;
width: 340px;
}
template.css line 653
2. There is a drop shadow that can be disabled in the admin of the module. Perhaps this will help? If not please post a URL so I can get a better understanding to what you are referring to.
Thanks,
