I can't help with the PCMCIA drive but for the webserver set-up you'll need to ensure you have apache2 installed. To install this, either use the Software Manager or start a command prompt as root and run:
yum install apache2
That installs the webserver, to start the webserver you'll need to type:
service apache2 start
To start the websever by default (at boot) you'll have to type:
chkconfig -levels 35 apache2 on
The website files will need installing to /var/www/html/
You will also probably need to open port 80 on your firewall.
There are loads of sites covering simple apache installs: have a trawl around google for info. There are also a few sites doing Pod casts on this subject - here's one:
