Trouble with domain settings

I am having so much trouble with my new domain.... a few days ago, i finally got myself a domain name, so from www.berkatrice1.blogspot.com my blog became www.berkatrice.com

but i never realized it would be so much trouble! i dont even know if i should reset my feed settings, blogcatalog settings, adsense settings, and everything else...

argh!!!! i hope i figure this out soon!
