Form CSS Issue?

Most of your issue is coming from the label rule on line 202 of your style.css file.

[css]
label {
    background: url("images/dash.png") repeat-x scroll left bottom transparent;
    color: #252525;
    cursor: pointer;
    display: block;
    float: left;
    line-height: 18px;
    margin: 6px 16px 0 0;
    padding: 0 2px 5px;
    text-align: right;
    width: 120px;
}

Also, the custom rule on line 332

[css]
.gform_wrapper .top_label .gfield_label {
    display: block;
    float: left;
    margin: 5px 0 4px !important;
    padding-right: 20px;
    width: 100px;
}

That's adding the dashes that you see and is overriding the default "top label" form settings. It's also forcing the weird label width. You should be able to remove those blocks from your CSS and see an immediate improvement in your form layout.

Line 652 adds the bullet "arrow" image that you see.. if you remove or override that then you can get rid of the bullet

[css]
.entry ul li {
    background: url("images/menu-bullet-right.png") no-repeat scroll left 7px transparent;
    list-style: none outside none;
    margin: 0;
    padding: 0 0 0 14px;
}

if you don't want to remove it, adding this to the end of your theme stylesheet should override it.

[css]
.entry .gform_wrapper ul li {
    background: none!important;
    background-image: none!important;
    padding-left: 0!important;
}

lastly, removing the rule applied to the span on line 655 will get rid of the last dashes (background image) being applied.

[css]
.entry ul li span {
    background: url("images/dash.png") repeat-x scroll left bottom transparent;
    display: block;
}

Good luck with it.
