Both of those are a part of the benefits you get, once you've purchased a paid plan for your site. During the purchase, you'll be able to select the option of removing the spruz branding. Once you have a paid plan, you put in a support ticket to let them know you have a domain you'd like added for use on your site. If you don't already have a domain, you can opt to purchase one through Spruz when you upgrade your site. Otherwise, the support ticket method is the means to go, and in that ticket, make them aware of the domain you have, and they will give you the info needed to set it up correctly at the place you purchased it.
