Extra Space after Each Entry

That looks to be a styling issue caused by having too generic of a CSS rule.
.post {
padding: 35px 35px 25px 0;
}

is the offending CSS. Try the following instead:

#content .post {
padding: 35px 35px 25px 0;
}

This actually occurs before id=”content”. It occurs inside the id=”breadcrumbs”.

I attempted what you suggested with no change, then I also tried the following with no effect:
#breadcrumbs .post {
padding: 35px 35px 25px 0;
}

Then I realized that the issue was the right-side padding. Fixed as this:
#breadcrumbs .post {
padding: 35px 0px 25px 0px !important;
}

Thanks!

I think you misunderstood/misread my reply. This is caused by the generic

.post {
padding: 35px 35px 25px 0;
}

rule applying to the breadcrumbs in and to the stuff in #content. You should restrict the wide casting CSS to what I had suggested (it works, I tested it via firebug). Using the!important flag is a little hacky (overuse can cause unexpected results).
