Do you have firebug? It will tell you exactly what classes have the borders and such so that you can then remove it. Like it says:

.cms_widget {    -moz-border-radius: 5px 5px 5px 5px;    -moz-box-shadow: -2px 2px 2px #C8C8C8;    background-color: #F1F1F1;    border: 1px solid #C1C1C1;
etc

So either go edit that, or add something like:

.cms_widget {
    border: 0; }

Do that for all borders/backgrounds you want to remove.
