I study multimedia and for making websites you can use:
- If you want to make a nice basic page just with some lines, use Illustrator it generates vectorial images wich are of very high quality and don't take in much space.
- If you would like to use a lot of blends and images , use Photoshop it is still the best program on the market.
And my advice would be make your site in flash if you like animations if you don't just use dreamweaver then.
And if you have any questions about Illustrator or flash or dreamweaver just send me a PM

P.S.: if you could get your hands on CS3 that would be great, i use it myself and it has a lot more options then CS2
