Accessibility Concerns

As I learn to manipulate HTML and NVu, I am focusing on the compatibility of flash and other multimedia files for my site. I am also want embed a screen reader for the site. I haven't completed much research on embedding screen readers on a web site but I plan on doing so this week.
So far, my site is simple. I plan on creating games and reading assignments that will be available for download, mostly in the form of word documents. Plans for my site are as follows:

• ReadFun (Reading Comprehension Website)
• Home Page (Overview of site and links to other pages)
• About Us (Creators of the site information)
• Students (Overview and games) (Pages: Reading, Phonetics, Spelling)
• Parents (How parents can help, downloadable content and resource links)
• Resources (Links to other related sites)
• Lessons (Games and other educational content)

Any suggestions are appreciated!
