ok so just looking through firebug tool i can see lot of margin issues and css floats thing
just cant exactly fix it with firebug though
but i will try to give u maximum info u need to fix it ..

Great i am glad it worked out,

for drinks haha 🙂 someday my friend someday

So this is standard wordpress upload, so going back to my very first comment
you can define width height in settings > media

u can define your settings, the other options r wordpress media presets which automatically detects your upload file dimensions and propotionally gives you width / height options

if u can post an actual link of the post, i can give you more accurate css

it is almost center 🙂

.wrapper {
margin: 0 auto !important;
padding-left: 0 !important;
}

remove padding-left:0 !important;

margin: 0 auto does the center trick

cheers

<script type="text/javascript">
  jQuery(document).ready(function($){

$("ul li:last-child").addClass("my-last-menu-item");
}
</script>

so you would have to define ur ul what ever class/id it has and add
http://code.jquery.com/jquery-1.7.2.min.js

in ur header before the script

and than create the my-last-menu-item css class
