When you find that the content you want to create is not a set of links, a single image or a basic table you can use the Text/HTML to create just about any snippet of text or HTML that you may need. Use it for a simple paragraph or if you want something a little more custom like an image with text wrapping around. Its also good for creating just a simple paragraph of text. Just copy from the old page and paste it in the Text/HTML editor.
When all else fails you can probably use this module to create what you want using its editor which is like a mini word processor. You will probably use the Text/HTML module more than any other module available. With it you can create a table, insert an image, type in plain or formatted text, created bulleted and numbered lists, left/center/right align your content and create hyperlinks. Whereas all the other modules are for creating a number of specific types of content such as a bunch of hyperlinks the Text/HTML module lets you create one or more of various types of content.
