Well, as far as the website goes, you could always use a something like blogger. Granted, it wouldn't have the nice newest, next, last, first, lay out of your typical web comic, but there are several people that use a free blogging site to host their comics.
If you are actually wanting to setup your own site, I'd be willing to help a little.
Did a bit of Googling and there appear to be some pretty decent free CMS's for a webcomic.
Comic Press seems to the best of them so far and is apparently what PvP online uses.
A couple of other scripts that look promising.
