OK, so first off you're going to get a lot of "Opinions" that will range from 'You Must' do all these changes to 'If you can't drive it the way it is, You're not a real man'....so maybe that's a little extreme, lol. 
Seriously, people either believe in making mods or they are totally against them it seems.
Here is what I did and why,
-Bigger front and rear Hellwig sway bars...because they make a very noticeable difference and they are fairly cheap, especially if you can do your own labor.
-Good shocks, I went with Koni FSD , but it sounds like you already have new and good ones installed.
-Align the front end with as much positive caster as they can get as it gives the steering a much better "feel" and reduces the numbness inherent in the factory steering.
I did all the above to make it more comfortable for my wife to drive. YOU WILL get used to the way it drives now the more you drive it, however in our case my wife might drive 1-2 times a month and the above changes makes it drive closer to the way her SUV does and makes her much more comfortable. Good Luck !
