If you are left to make the decisition on a web server. This is a tuff call. Some people really like Netscape enterprise server, but a free webserver that i think a Majority ? of us run is Apache. It has all the features you could want and more. plus its free and there is more then ample documentation for it. (If you go the apache route check out Oreilly's book on Apache) its a great book and not all that big either.
I might also add that you may want to start brushing up on regular commands and text editors! But I also recommend Apache! So many options, so little time....
