Hi I need some advice on getting started

Hi, I've just installed website baker, latest version, but I'm really confused as to what to do next and I'm wondering if it's all installed correctly. I can log into admin and create a page, but writing a page and selecting one of 4 templates is about all I can do. Theres loads of files loaded up to the server, but I don't know how I get therse to work.
For example, templates. If i go to admin to browse templates, it wants me to browse my pc. Same with modules. Now I have activated the modules, but I can't see any modules. All I can do is write text. The modules folder is installed to the server, the structure is as it should be.
So if i go to the url, I get a page with whatever text I put on it, but how does anyone log in and create their own pages? It's all very baffling. Can anyone help here, maybe give me an example of how to get started?
Thanks in advance.

Just been trying again, and I just don't understand it at all. For example I've gone into manage sections. I've added blocks. where are they?
I've created two pages. Ome is just a plain old page, the other has a red header by using the all css template.
Now if I go to my url, i get the plain old page. the only way of viewing the other pages is via the browser. But what can anyone do with this? There's now way of logging in, or using any of the functions. Only admin can get into the site and then there are no modules except the text editor. I'm missing something here, what is it?
