Honestly all of Twallan's mods are pretty awsome. It's a learning curve though. You just have to read about the individual mods he makes and how they are used and then decided which ones you think would help your game.
I personaly am using 7 of his mods so far from http://www.the-isz.com/nraas/ and it seems like every time I look at info about one of his mods I DONT have, it looks like something that would make my game more fun.
If you want something dirt simple without all the other options and configuration of the mod, you may want to try my Friendly WooHoo and Teen WooHoo mod here: http://gnautylilgnomes.com/forum/index.php?topic=2567.0
It's XML so you install it and forget about it, no wondering about the configuration or anything else.
