Nah don't be afraid of asking for this.
First of all, everything you could do via csv edits can be done via a CE edit, cose is just memory change (clientside).
As CE is a lot easier to use and more noobfriendly, I would start with that.
If you don't want to create your own script, which isn't easy if you are starting, you can make a fast look at this thread

.
Also, you should know that, with some updates (patches) of the game, the scripts need a update, check this thread for knowing how to do the updates:

Well, that's it, once you know this you can start searching for tutorials on csv, but the difference, as I said, isn't too big (the only hacks worth it are changing the graphics, mass spawn, and reducing the lag deleting the animations).
Hope I helped ^^, and welcome!
