This is an unsupported skin, so changes from its developer won't be happening. Consider that before you commit to using it.
The skin doesn't provide a convenient way to alter the CSS of the album, so the only choice is to edit the skin's template files. Choose the skin, then Tools, Skin developer, Edit skin files. Head for the tab for common.css. The "all-caps" appearance of the home link, for example, is on line 359. Either delete that line, or change it to text-transform: none;
To change other things, like text size, will require similar tweaking of the template files. You'll need to learn how to use the developer tools in your browser to identify which CSS classes are affecting which display items, so you'll know what has to be edited in common.css.
