Here is the Beyond BT Guide to the Seder which goes through the basic halachos of each step of the seder.
While getting ready for Pesach, you might want to give Rabbi Welcher’s Preparing for Pesach a listen.
The Absolut Haggadah, a refreshing blend of humor and commentary trying to uncover the pshat (basic meaning) of the Haggadah has been updated. You can distribute it to anyone who might be interested.
This Seder guide is very helpful. Thanks Mark.
