Scribus DTP question - text flow

I am trying to get to grips with Scribus, and am loving it, however, there are a few things I can't find in the documentation.
I am trying to put together a 30 page document, that has many common features on each page, however, occasional pages are completely different. I want most of the pages to be two colum text pages with text automatically flowing from one collumn to the next, and from one page to the next, but every now and then a page will have a full page graphic. I am not sure how to set up a template to take a text file in and make all the pages, and then break that up with individual odd pages. Do I have to do each page by hand, and select the template I want?
Thank you!
PS There are left and right hand pages too!
