Tom Harmon Ministries
This sight contains some very good preaching full of scriptures and deep truths. He also has a few Bible studies you can print out. I am currently doing the study on Spiritual Warfare.
Through HELP Ministries you can support native missionaries as they reach their people. These native missionaries have an advantage over American missionaries because they already know the language, culture, and are used to the living condition of their country. I've been privileged to meet 12 of these missionaries and I highly recommend them all.
