I don’t mean to be rude, but using standard settings will not result in anything of quality for most people.
You should be able to get good Windows Media and Flash 8 out of the Adobe Media Encoder. If you want good results with Quicktime, you really need to purchase Sorenson Squeeze. By the way, their latest patch fixes all problems using the Cineform AVI.
Why did I suggest those sizes? Because most people don’t want to download 100MB files to see a two and a half minute trailer. They might download a third of that though. It depends on the audience.
Apple pays big bucks to compress those into the smallest files possible while maintaining the quality. You can not afford such software is my guess. So Get Sorenson Squeeze to use the Pro codec.
If you can afford the space to put up different versions, then feel free to do so. It all depends on your audience.
If you tell me how long your movie is, what is the minimum size you can accept for your web site, and I will give you a suggestion for a starting point for Windows Media. But the real way to do this is to bring the file size down by reducing the data rate to the point where you hate yourself for going that low and you back off a bit by increasing the data rate.
