You will find an introduction and outline of Joshua, here.
Here is a prayer from the Book of Common Worship to use before reading:
Eternal God, your wisdom is greater than our minds can attain, and your truth shows up our learning. To those who study, give curiosity, imagination, and patience enough to wait and work for insight. Help us to doubt with courage, but to hold all our doubts in the larger faith of Jesus Christ our Lord. Amen.
