Hello, came here from network. Here are some CSS fixes for you. Just go to the custom CSS page of customize style, and paste these in the custom stylesheet box. (I also included one for overriding some code that makes the subtitle & pagetitle of your style automatically be in lowercase, but if you don't mind that, just delete that one.)

/* To get rid of text in uppercase */
#title, .navigation, .entry-title, .datetime, .metadata, .metadata-item-location, .metadata-item-music, .metadata-item-mood, .tag, .tag ul, .tag-text, .entry-interaction-links li, .comment-poster, .comment .footer, .month h3, .month th, .page-tags .tags-container h2, .page-icons .icons-container h2, .module-header, .journal-name, .journal-website-name, .module-navlinks ul.module-list, .manage-link, .manage-tags-link, .module calendar th, .module-calendar td.empty-day, .module-calendar td.entry-day, .ContextualPopup, .ContextualPopup .Relation, #lj_controlstrip td, #lj_controlstrip input { text-transform: none !important; }

/* To get rid of text in lowercase */
#subtitle, #pagetitle { text-transform: none !important; }

/* To insert padding above pagetitle (adjust "1" to value you desire, e.g 0.5em, 2em, etc. */
#pagetitle { padding: 1em 0 0 0 !important; }
