First part - change the sidebars height to auto or remove height property completely (auto is the default setting for the height)
#main #sidebar {
float:left;
height:auto; / Add this line or remove height completely /
margin:0 0 0 10px;
width:330px;
}
The title's h3 is set to display as a table. Set its width to 100%
.widget .inside ul, .box h3 {
display:table;
width:100%; / Add this line /
}
