[Theme: Destro] Header not centered in destro theme (p.2) or actual size

Hello, I am attempting to configure the header for my site and am having some trouble. I have tried to follow the posts on this page and have done the following:

I substituted the code as suggested on the post, No logo without upgrade, but could not figure out how to “tweak” the alignment with Firebug. This allowed me to at least see the image, though it isn’t center or the right size.

Then I tried to follow the suggestions in the post, header not centered in destro theme but was unable to. I would like my header to look similar in alignment and placement as the author of this site.

Thanks in advance!
