The widths on these 2 pages that are throwing off the layout are bugging me lol....know where I should look?
forum.php
adminappreport.php
On lower resolutions, yeah, that can become a problem. There are some bugs that come out in that template that need fixing with regard to lower resolutions (1024 and under).
As for Twitter and News feeds, you'll have to add them manually (it's like this for all games, not just lotro). Head to Admin > Menus > Twitter Feeds, and also RSS Feeds to add a feed.
But you need to know what you're looking for. Twitter feeds require you to specify a search parameter (maybe something like #lotro), while RSS feeds expect an RSS feed URL (for example something like
http://www.lotro.com/feed.rss - I doubt that's an actual feed, just an example).
