Gallery theme issues.. a few more

How to:
1. Change the sidebar from left to right.
2. For some reason user login appears to be hard-coded in the sidebar. Any widgets added are placed below it. So how to remove the user Login widget.
3. Change direction of Main navigation menu. As of right now I can't get the menu to read from left to right. Instead appear right to left. So:
News, Community, About, Home.
Should be the other way around:
Home, About, Community, News.

Any responses appreciated.
