Well, now we are getting into questions about your self-hosted site at Dreamhost, which I can't help you with. But I can suggest some places to get that question answered!
I'd start here: http://codex.wordpress.org/Photoblogs_and_Galleries and in general: http://wordpress.org/support/
Tons of resources there to help you get the styling you want on your new blog. Hope that helps!
