A Beginner's Guide to HTML (NCSA): A good, basic tutorial, including images, tables and web design. Links to other resources. Reads like a text book, but the best introduction to HTML I've seen.

Netscape Communicator/Composer: Netscape's Browser (V. 3 & 4) comes with a WYSIWYG (What YouSee Is What You Get) editing tool. Not as much control as a decent HTML editor, but some people don't care to write the tags themselves. (Gasp!)
AOLPress: A free WYSIWYG web authoring tool from the folks at AOL. Good visual design tool in "MiniWebs". Built in FTP for AOL users.
Arachnophilia: One of my freeware favorites. Tools for forms, frames, tables, sound, etc., etc.,etc.

CyberDuck: A very nice FTP tool for MAC OSX.
