Drupal has a pretty tall learning curve, it's better to know some of the more popular modules out there before jumping in and trying to build a site with it. Check out the lullabot video series (worth every penny) for a good primer. I picked these up and made my money back x10 on my first drupal site. Drupal does require a little pre planning but then again every project / application does, that being said you can add new modules anytime you want and remove them too (little more time required here). You don't need a ton of PHP knowledge almost anything you need to do with drupal already has a module written for it. Yes you can modify any of the existing modules as they're written in PHP, beware this takes a strong PHP knowledge most of the time. Good luck...

Change it how? Change the look of it? Change the text used? You can add your own information to the end of the current breadcrumb by adding a simple php print statement to the end of your breadcrumb print. If you want to change the separators you will have to modify the preprocess function for breadcrumb variable. You can get this information using the theme module.

I don't think you get all three if you want really easy, you can try single template Volusion. Basically you only need to do the markup for the site. Fastest is relative to a lot of different things. If your Drupal / Ubercart setup was slow you probably need to change somethings with your configuration, possibly your hosting. A couple overzealous views in drupal can kill the performance of page loads. I don't think "best" is a quantifiable term.

I like Drupal.
