I'm a pretty green user of the CS, I can make a vanilla house mod, but that's pretty much it. However I want to create a few mods for my own use with quests and npcs, therefore I need an idiot's guide to doing those things, and I do mean idiot guide. Also pointers to the required files for silent dialogue and, if I remember correctly, there is some problem with the patched CS and voice files...

:icecream: Thanks in advance, any friendly advice is also appreciated

There's a good http://tesalliance.org/forums/index.php?/forum/14-npcs-ai/ that can help you get down the basics. There's also a good "My First Quest" type walkthrough at the http://cs.elderscrolls.com/constwiki/index.php/Click_by_Click_Quest_Tutorial.

For getting around the patched CS and voice files issue, you'll want to have a look at the http://cs.elderscrolls.com/constwiki/index.php/Dialogue_Tutorial at the CS Wiki. Everything you need is linked & explained there.
