If it's a 4wd 1500 all you need to do is use lift struts (like Bilstein or similar) or use lift coils with the appropriate struts (like Eibach) so that the OEM range of motion is not changed.
Then all your stuff won't see any appreciable extra stress and you'll have nothing to worry about.
At 2" you could keep the factory upper control arms or get lift specific arms, that's kinda at the threshold of where they're not a bad idea but not absolutely necessary. Everyone's got their own opinion on that but the factory alignment cams have a fixed range of motion so the more you deviate from stock height the closer to their limits you might come during alignment. From my own experience and plenty of reading, not a big deal around 2" or less of lift.
