Before you start

Can anyone reccommend a case study, or live site, of Drupal being used to develop a (college level) school atheletics website?

I'm new to Drupal and am beginning to design a web site that has two primary types of information:

I have not committed to shopping cart yet. I've been looking at Ubercart but am not sure how shipping labels are printed. I'd like to integrate with Quickbooks if possible. Should i look beyond Ubercart? I would really like to do this right the first time! any help would be appreciated. Thanks!

Upon Istalling drupal v7.37 using Acquia Dev Desktop 2, I came across this issue, where It cannot write file to the host file in my local computer C:/window/driver/etc/host.
.
Is there any way I can fix this? I have given permission to my local account to have full control over this file but I still have problem with it.

Please I really need some help on this.

Thanks in advance,

Please, as someone who doesnt know about drupal, and want to learn to use it to build a website. How do I learn it very well? A sort of tutorial and videos. Thanks.

I have lots of questions about what Drupal can do, and a plea for guidance on the basics of choosing from the many components available to create different pages that do what I want.
