I think all of the advise given above is excellent. To really catch it well it helps to have a long lens but then you do need to worry about motion blur as totality approaches. The only other thing that I would add is that there are many ways to shot an eclipse. Some feature the contrast between shadow and light. Others attempt to capture detail in the face of the moon. Finally you can attempt to capture the special effects of light around the edges of the moon. All are great fun! Good luck. May there be no clouds in your night!
