TSLRCM. Let's not forget Morrowind, GND-Tech has a mod list for that too.
Keep in mind though that the expansions for NWN 2, particularly Mask of the Betrayer and Storm of Zehir, are the best parts. With that being said I advise finishing NWN 2 first, and then porting your character to Mask of the Betrayer since it takes place right after NWN 2. Also you might want to play something like
Icewind Dale - NWN 2 before Storm of Zehir. As the name implies it's an unofficial Icewind Dale remake (and a very faithful one). You can make a party of four, and then after you beat it, port those four guys to Storm of Zehir which is a high level campaign anyway. This means more playtime, more leveling up, and thus more awesome abilities.
I must point out that in both Icewind Dale NWN 2 and Storm of Zehir, there is no single protagonist. The four characters you make in the beginning are all the protagonist, and you can use all of them in dialogue. This is great since you can make one of them have high Diplomacy, another have high Bluff, and another have high Intimidate, so that you can choose the appropriate one in dialogue. Storm of Zehir has so many contextual skill checks so that no single character can meet them all. You can make less than four characters if you want, and up to six in IWD, but Storm of Zehir only allows four so I'd stick with that.
I can help you make effective characters if you need. NWN 2 is pretty much all I've been playing as of late (revisiting it and the expansions and trying out some mods soon).
