I'm glad you're shooting in RAW, it's the only way to go IMHO.
You're right, when shooting raw the image may not appear as sharp as the JPG but all the data is there.
When shooting JPG the camera applies sharpening, brightness, contrast, etc. based on the picture style you select and then bakes those settings into the image.
In Raw, you're dealing with the "raw" data.
None of the information like exposure to some degree, white balance, contrast. and much more, as well as the sharpening is locked in yet.
When you open an image in ACR it automatically applies a little bit of sharpening and you can apply more, but I would use it sparingly.
Sharpening an image should be the last step in the process, and you sharpen specifically for the output.
You would sharpen more for print than for the web for example.
