At the risk of repeating, I will summarize the available options to reduce the file size:

Move out all your Javascript and inline style sheets to external files ( this induces caching for the end users and the search engines don't need to crawl through tons of code to reach the meat of the matter - your content).

Optimize your images and Flash files - Images can be optimized without sacrificing on overall image resolution. Use Vector graphics more in Flash if possible. Bit map images add more to the file size than vector images.

Tables in HTML add to the clutter. Opt for CSS based table-less positioning of HTML elements. This method obviates the need for long winded nested table clutter.
