Jason,
May I suggest a quick trip to the HTML, Graphics and Programming forum.
There are some excellant guys in there, namely Augmented, iCraig, py33yn, Inquisitor (to name a few) that are always happy to advise.
The most important thing to remember when constructing a website is to make it viewable in as many web browsers as possible. The best way to do that is to hand-code standards compliant HTML/CSS (more info available at w3.org). Using the MS Office tools will most likely produce a website fit for viewing in Internet Explorer 7, but will just not work in the dozens of other browsers out there which will make around 50-60% of people turn away from your site as the types of people you are making your site for will probably have the good sense to use firefox/opera/other non I.E. browser.
If you want to go one (hundred

) steps further, you could look at picking up PHP/MySQL as well to make a database driven website. This is highly reccomended if you plan to be updating your site often. (Disclaimer: I do NOT advise this until you know what you're talking about with HTML/CSS).
It will be a lot of work and much more time to make the website by hand, but you don't half get a good feeling when its all done and the end product is usually 100 times better than using tools like the ones in Office.
Edit: If you want to get up and running quickly, I suggest you use the Joomla CMS (
www.joomla.org). Its bulky and has more features than you'll ever need, but it's relatively well coded and is cross-browser compatible. I'd only use this in the short term though while you got your coding skills together
HTH
