Yes, Joomla seems too much for what you're trying to do. For a site with only a few pages, I've been using
CMS Made Simple for a couple of sites. Not as "blog centric" as wordpress (which I use also for a blog) or blogger, and you can import designs from
OSWD and customize pretty easily.
It comes with a news manager (which I haven't tried) and has many other extensions you can add like a photo album, etc. if you want. It has an admin piece that you can set others up to add/change content...and can manage the content pretty easily. Great community/support/forum also and is free!!
This is a
small site I did for a friend using the stock install and just customizing the css templates, etc.
