Hello,
You can increase logo using this code in custom.css file:
.header-type-3 .logo-with-menu img {
width: 300px !important;
}
.header-type-3 .main-nav .menu {
width: 700px !important;
}
Concerning products order you should contact Woocommerce support as this is their configuration. Also you can refer to these articles:
