Thanks for the advice.
I got everything installed OK, though I used FrontPage instead of Fantastico. (I'm just more comfortable with FP after 6 years of use...)

I only have one question.
I've found a theme that I like, but want to tweak it just a bit. (add stuff into the footer, remove one small thing out of the header, drop some code into one of the sidebars...)

What am I doing wrong?
