The measurements I've seen all seem to be after grinding.
Strength is controlled by the amount of beans, how coarse the grind is, and how long they brew. Water temp comes into play only a little, IMHO. Balancing the three controls strength and doesn't get bitter.
The directions you got were good. I'd measure the beans again and grind them and see what the volume is after grinding. You might see only 3 tablespoons depending on the bean.

I think the best coffee that I've made myself was in an insulated French press, where I controlled the temperature and ground my own beans (not a burr grinder though). While it was good coffee, the juice wasn't worth the squeeze for daily coffee making. I've also gone to local roasters in the Dallas area to get coffee that was roasted within a week or so of me actually making it. In the end, I wasn't able to tell much of a difference in the recently roasted vs the "unknown" roasting date you get at the grocery store.
My current setup is a Bonavita Coffee Maker (at the time it was certified by the SCAA to brew coffee at the appropriate temperature) with Gevalia French Roast. While I'm sure there is much better coffee out there, the Gevalia tastes good to my unrefined palette.
In the end, I was never able to get scientific enough to prioritize temperature, preparation method (drip vs press), roast date and grind consistency (coarse/fine, burr/standard) to be able to get the most out of my coffee. After thinking about it, I think I probably put too much emphasis on roasting date, when there were other things I could more easily control.
Went to the local asain food spot and picked one of these since this thread has been making people spend money I figure 8 bucks wont hurt for an experiment.

They're nice but they can overheat the coffee and/or are very inconsistent. You're using uncontrolled steam at an unknown pressure and temperature. I love mine when I can get something good from it though. I'll half ass froth warmed milk and make a ghetto latte type deal. I find they benefit from a finer grind.

just got a french press/grinder set up. really excited, now someone send me some really good coffee so I know what i'm missing
