This is what I did to fix issue number 3. Is there a better way?
In Custom CSS
.product .sku_wrapper {
display: none !important;
}
.product .leave-feedback {
display: none !important;
}
.product .need-help {
display: none !important;
}
.reset_variations {display: none !important}
.product-share{border:0px !important;}
.product-share{padding-top:0px !important;}
.product-share{margin-top:0px !important;}
.panel{margin-bottom:0px !important;}
