What do I need for this Website

Hi,
I am making a plan to make an website that will have an radio fucntion that will play whatever I would like and the radio would have different channels. Also there will be an Forums section and an article section. The article section woulbe be articles that I wrote.

I would like some advice on what technology should I used to acheieve my results. Also what type of web hosting would I need? From the above specs would I need a database? If so, why?

Thanks

Suggest that this question is moved to another forum as it is not specifically related to IIS. Suggest start with Misc questions as there are a few options.
