Its really difficult to explain how to do what you want, there are so many different ways to achieve the same thing.
The following is for RAW files. Jpegs do not need camera profiles applied.
G0 to a imported raw image, highlight it, and go down to the camera calibration section in the develop module. Click the drop down selection in Profile where it says Adobe Standard and select the profile that you set in your camera. Try the different profiles to see which is best. Then, adjust sharpness, NR, and the other sliders for the best image.
Setup your options, in edit / preferences / presets. Check the appropriate blocks to make your default settings specific to a particular camera, a particular ISO, or for all.
Then, click develop / set default settings / update to current settings.
Now, when you import a raw file, it will receive those settings, or the settings for that camera / ISO that matches. If you set it by ISO, you will need to set the default import settings for each ISO. This is only the beginning, since you can create and apply presets galore as well. It literally takes a book to cover it well.
