Do NOT get wrapped up in all that stuff (unless you want to.) Before you know it, you're photography will be a science project. You can easily start down that path but it's a very slippery slope. The next thing you know, you will spend all your time evaluating the characteristic curves of film, reading up on densitometry, testing film and paper combinations, etc, etc.
To start, just learn how to expose an average negative. Prolly over expose 1/2 to 1/3 of a stop and develop normally. If your highlights (where you want detail) are getting blown out, reduce your development time in 10% increments.
Then, you can take that negative and post process (photoshop or in the darkroom) until your hearts content; make multiple versions, using different paper types, printing methods, etc. I don't recommend trying to get a negative to match a certain paper and printing style. Today you may want to Lith print the negative and five years from now, you may want to make a digital negative from your original and make a Kallitype print.
The key is to get as much information in your negative TODAY.
Extra exposure isn't a magic bullet, its just one way to do things.
If exposure is accurate, there is no real need and minimizing exposure has its pluses. Faster shutter speed, smaller aperture, minimizing grain; all good things are they not?
