I wouldn't keep the indiemade.com url, for branding purposes.
To make the www work in front of your website, forward the your domain root "domainname" to your www.domainname.com and you should be all set. Since I don't know what registrar you use, here are custom domain name instructions with additional info to forward the root domain to your www address.
