This is the right forum of course. Fistly check out the toolset tutorials on the Bioware forums.
Here and here are good places to start:
http://nwn.bioware.com/builders/toolsetintro.html
http://nwn.bioware.com/builders/modtutorial.html
These will cover the basics.
Download some modules on the vault (try some top rated ones) and see exactly what can be done with the toolset alone or using hakpaks (modifications to what is actually in the game...additions if you will).
http://nwvault.ign.com/Files/modules/
Experiment for yourself. Check out the coupled scripting tutorials to add life to a module. Any questions should be taken to the Bioware builders forums (which you should check out anyways) or here, but I'd recommend the official forums as many starting questions you have will already be there and already answered for you to see.
Don't be discouraged!
