If you're anything new to Linux, do expect frustrations. I have installed using the How-To Falko created and ISPConfig till developed on my server (x4), and on remote servers (x3) without problems on Fedora 3. The only problem I got was due to my stupidiy and the person who install linux on the remote server.
You must know what logs to look at in order for the folks here to help you. Some of your question my have already been posted here. I know I have lost some hair by trying to solve my problems, but that's just part of using an unfamiliar OS.
I hope you get your problems sorted soon. Trust me, when you get all the problems ironed out, ISPC is a treat!. Best of luck!
