Lightroom is a non-destructive editor . That is to say, you can do whatever changes to your RAW files and until you export them there has been no change to the actual RAW file. You can choose what type file you export as, but PDL is right that jpeg is by definition an 8 bit file type. There are plenty of other file types that can have more color depth.
As to converting an image from 8 bits to 16 bits, I'd say that is just a function that changes the container a file is in. Something like pouring a liter bottle into a two liter bottle. What you have doesn't change, but the container changes. Which means that you have the same limitations that you have with a normal jpeg image.

I would say that if you shoot with settings that pump up sharpness and saturation -- say Bright or Vibrant -- your jpegs will be what they are. If you shoot with a Natural setting, you can add some sharpening or vibrance in post, but it is awfully hard to take it away. White balance issues can be corrected somewhat in post with jpegs, but you definitely have more leeway with RAW. In camera noise reduction is abysmal and should be avoided like the Plague.

The only time I really use jpegs from the camera is if I am on a family vacation and I know that I am shooting too many images to really spend time post processing them. Even then, I will switch to RAW pretty quickly if I am in a not so great lighting situation or I really want to maximize the dynamic range. While out of camera jpegs look pretty good, there is an extra 10 or 20 percent dynamic range/high iso performance that gets thrown away and you can't get it back. For most images it probably isn't important, the trick is to know when it is and switch to RAW then.
