I do this for a living, so consider this a professional critique and nothing more:
1. Put the links on the first page at the top of the page so a person does not need to scroll to get to them, and keep them in the same place on every page so a user knows where to go to navigate to different pages.
2. Keep the typeface family for the entire page the same. You have a serif and sans-serif typeface (specifically, Times New Roman, and Tahoma, as it is rendered in my browser) on the same page, with no apparent distinction as to why. Make everything a sans-serif typeface specifically designed for web page presentation, such as Tahoma. The reason being that serif typefaces generally do not display very well at the low resolution of displays (75dpi and less).
3. On the schedules page, remove the three-dimensional borders from the table (they make it look "old", i.e. out-dated) and change its width to the width of the page (i.e. make it 100% instead of 800). If you switch over to CSS (see below), you can make the borders of the table a single pixel to help align the user's eye. However, I don't recommend creating vertical lines because that will create a box of boxes, also known as "negative space", and will cause it to be difficult for the user to actually read the words inside the table.
4. Remove the background picture. It's gray, which makes it dreary to begin with (to me, it makes me think of rain), but it also makes the page appear amateurish. Also, it repeats in the lower 100 pixels or so on my browser, making it look very strange. Just set the background of the page to white.
5. Once the background picture is removed, reduce the weight of the main text on the main page to normal, from bold, since it's probably bold so you can see it over the busy background graphic.
6. Remove the setting of the width of the main, invisible table to 800 pixels. There's no need to artificially restrict the width of the area. Make it 100% so people with higher resolution settings can see more.
7. Remove the italics from the main link, again, due to the low resolution of displays, italics generally do not render well.
8. Remove the white border from your main logo (you can do that by filling that space with some odd color that does not appear anywhere else in the logo, save the graphic as a .gif, and set the odd color as the transparency color while saving).
9. Perform the same step on the exploding clay graphic, but you will need a slightly more sophisticated application because you need to fix each frame of the animated .gif.
Additionally, think about changing over to using cascading stylesheets. I looked at the HTML and you have some non-existent attributes (such as "font face") set, and it will make it easier to maintain a consistent look throughout the pages.
HTH. If not, ignore.
