How do I go about changing my host in my DNS settings?

I am currently with shopify and need to change the host on my third party domain. A local company was once doing our hosting for our website and have decided they would no longer like to host us. Should I move my host to Host Gator or should I try to get hosted by shopify? How do I change the name server. We also have a Email system with them and would need to get that moved over.
