Would appreciate help.

I'm brand new to modding and making units and things for Civ 4.
I realize that they are pretty complicated stuff, so instead of asking you
to explain it, I'd be fine with some tutorial links (if possible). Please?

There is a modding tutorials sub-forum. Here's a link.

XML is easy and the best place to start. I recommend learning it first and playing around with it a bit. Next is python and then C++ (or SDK), which are incresingly harder but more powerful.
