For evaluation of the CMSes, definitely go ahead and use the automatic installer from your host. However once you've settled on the CMS of choice for you, I strongly recommend you remove the auto-installed version and manually install the copy from drupal.org (or joomla, or whatever CMS). Unfortunately usually you'll end up with problems down the line if you use the auto-installed ones - for instance a critical security patch may come out for the CMS (e.g. something that could easily allow your site to be hacked), and you won't be able to install it manually without breaking the auto-installed version (and the auto-installer may not have the patch available for many weeks or even months), or other unforeseen glitches can come up.
I can't speak for "every" CMS of course, but most (e.g. Drupal and Joomla, etc) now have very easy to use installers built in - just upload the files to your server, set up a database with your webhost's interface (e.g. in Cpanel, Plesk, etc) and then enter the database name, user name, and password into the CMS installer when prompted, and that's all - should immediately work.
I agree, Joomla is difficult to understand in regard to setting up the content of your site... one bit of guidance I can give is that in Joomla (to my understanding from the site I made with it), nothing is a page on your site until you assign it to a menu. You also have to set up Sections and Categories within those sections, and then put your content inside of those (and link that content to a menu in order for it to be accessible on the site). I never tried out the Dreamweaver plugin for Joomla, but I agree hand coding is the way to go
What I suggest is to make your full site theme first however you like, then open up a Joomla template and extract whichever dynamic variables you want, and place them in your own template... set up your template files to Joomla's requirements, and there you go 
The modules aren't too hard once you get the hang of it (so long as you learn to differentiate between Components, Modules, and Mambots ... just go to the appropriate installer page by clicking it in the top menu to the far right "Installers". Where it says "Upload Package File", upload the zip/archive file you downloaded for the component/module/mambot, and it installs automatically. Then view the Component, Module, or Mambot menu, locate the newly installed module to use or configure it.
For Drupal... let me know if you have any questions and I'll be glad to help you get on track.
Here's a site I'm currently making with Drupal for a friend/client: http://av.absolutecross.com (note: still in progress, may have some bugs and definitely hasn't been tested lately in IE6/7). The most recent copy isn't "online" yet either (I'm working on it on my local server). This is more of a static site, so it doesn't (yet) show off a lot of what Drupal can do on the surface (though some interesting things are happening under the hood). For the most part, the full theme was completed for this before even deciding on using Drupal to power it - I then just plugged in the necessary Drupal PHP variables in the right places to put real data in (which I just copied out of another Drupal theme). A few more detailed tweaks were made with extra tpl.php template files for a few minor details, and a few adjustments to the CSS were needed, but overall it was very simple.
In both Drupal and Joomla (and other CMSes) you never really need to make as complex of a theme as those you download to try out. Those themes have to be super flexible and support many possible ways the theme may be used (e.g. menus or blocks appearing on both the right or left or other potential places). Since your site only has to be the way you want it for your own use, you don't have to make your theme that complicated.
Also, here's a bit of a starter article I wrote about Drupal (I plan to write a lot more sometime soon): http://www.absolutecross.com/webmaster/articles/best-drupal-sites/
Good luck
