Hi Kim
Well done for using layers, that certainly is a step in the right direction for any website. I am also glad you use textual links for your site instead of boring old 'Click here'. Copy text is also pretty good (as it is your prime product)
However, your cream coloured boxes (on the right-hand side) overlap your slightly darker background by about 20(ish) pixels. Also these boxes look a little pokey and for the little they report, a waste of space.
This brings me onto the next thing. If a site can be too yellow, Your site is it. If you want to emphasise the site a little better without going overboard, then how about a khaki or olive background with your cream boxes? Have a gander at

At 800x600, you have horizontal scroll bars galore. 1024 x 768 may be getting more and more popular but a majority still use 800x600 (especially for what I assume to be your target market audience). Horizontal scroll bars just seems to burdening and will put a lot of visitors off.
Finally (and maybe I am just in picky mode now) Your navigation is very bland and blends in a bit too well with the rest of the site. Perk it up a bit so its easier for your prospective clientele to identify.
