Metering for B&W negative materials isn't nearly as complicated as many might lead you to believe. Really, the only thing you need to be sure of is getting enough exposure for the amount of shadow detail you want. There are many ways to get this; it depends on the meter you have, the time you have to meter and your approach. Nevertheless the goal is the same: adequate exposure.
Spot metering all the values and then deciding on a development scheme implies that you are using sheet film and have tested all the different development times you use. I do this, but I certainly wouldn't meter like this for roll film.
If shoot roll film and have no in camera meter and use a fancy-dancy meter like the L758D, you might be tempted to do a lot of averaging, comparing with incident, etc., but really, you just need to get the shadow values on the film. A spot reading of an important shadow value and intelligent placement of it in Zone II, III or IV according to your plan for that value is all you really need. You don't even need to meter a high value since you will likely develop the whole roll at your normal development time anyway.
Or, if your personality tends toward incident metering, you could just take an incident reading of the light (or similar light) falling on the subject and use that. You only have to compensate a bit for really contrasty situations. Incident plus a stop more exposure for contrasty situations, regular reading for normal and flat subjects.
In both the above scenarios you simply deal with contrast at the printing stage.
You'll be better off with one the above methods that with more complicated methods, especially starting out.
