I'm an umbraco newbie so I apologize if this is overly simple. I have a clean install of umbraco 6.02 and switched to MVC in the umbracosettings config file. I installed uBlogsy 3RC and loaded the patch. I'm trying to customize some of the output, is it possible to do this from within Umbraco's admin console? I only see what I believe to be only a few of the templates in there. I see there are many more CSHTML in the installation package. Or is there an easier way to change the output? e.g. I'm trying to add some basic stuff like modifying the header to include textbox input for examine search, a membership provider login control, etc.

I attached a screenshot of where I'm looking. I don't see where the header is actually being generated. Am I looking in the wrong place, or is there an easier way to do what I'm trying to achieve? Thanks in advance for any help.
