This type of update should be added as an edit to your question, so that everybody who reads your question sees it immediately. As an answer, it's hidden down here at the bottom =) Also - have you read the rviz docs: http://www.ros.org/wiki/rviz/UserGuide? What part doesn't make sense?

Do you have a LaserScan or a PointCloud? For rviz just add a display for whatever you have. They are named Laser Scan or Point Cloud.

Find the package which works for the 2d lidar you have. Basically this is the ROS driver for the lidar you have. That package would publish a pointcloud message which can be viewed in rviz. In rviz, you have to select proper fixed and target frames. Then add a pointcloud message and select the topic on which pointcloud message is published.
