Hello
1. To amend try adding the following to the Custom CSS field of your templates parameters...
.wrapper960 {
width: 100% !important;
}
2. It appears the logo image itself is cropped (

3. To amend you can set a min height to the showcase area by adding the following to the Custom CSS field of your templates parameters (edit to taste)...
#container_slideshow {
min-height: 400px;
}
