Organizing static content properly

Hello,

I'm in the process of migrating www.icaportland.org into Drupal. I've got Drupal set up at http://72.9.248.66/~oirvxhsg/ and it seems to be working perfectly. Before I start moving content into Drupal, I was wondering what the proper method of organization would be for the files. The desired result would be a hierarchy something like this (basically what is already at the original site):

Home (static)
About Us
- single static page with multiple sections of text
Join ICA
- page with two tabs: "Why join?" and "Online Registration"
Events
- page for each event
- three tabs on each page: "Visit" "Perform" "Sponsor"
Chakra
- single static page linking to multiple pdf's
Feedback
- single page with feedback form

I don't need everything laid out for me, but if someone could tell me how to do something like the Events section, I think I could extrapolate and do the rest on my own.

Thanks for your help.
