Right now I have the .ipbhost.com/ after my website. I have a domain without that, how can I get all pages onto that site? Or should I just have my domain redirect to this site?

To use your own Domain with a hosted package, please see this guide:

https://invisionpower.com/4guides/getting-started/community-in-the-cloud/using-your-own-domainsub-domain-r231/

and choose which of the two options you wish to use.

Changing the domain is automated in our system, but if it fails please file a ticket to Support.
