Portfolio Images + 2 other questions

Hi all,
I’ve had the Highend theme for awhile and it looks fantastic.
I have a few quick questions though.

1. On my portfolio page, when you click on a thumbnail, it only shows that picture. How do I get it to where you can scroll thru a gallery of pictures when you click on the thumbnail?

2. The blog page- how do I change the top heading picture that has the “My Blog” text over it? I have looked all over and cannot find where to change it…

3. When you click on ‘News Feed’ on the side bar, one of the posts isn’t equally spaced like the others. Where do I tweak it so all the posts can be the same height/width?

My website is: http://www.AutoBlissMemphis.com (it’s still a work in progress)

Thanks in advance!
