Answer 1

Just make it possible for users to visit your site with links (or any other text web browser), and you'll be 90% there.

If you do that, you can create a simple separated CSS file that doesn't have most of the images and has friendlier font sizes.

You might want to have shorter/smaller pages, with links to get more info only on request, to save bandwidth.

Other than that, use common sense.
