A little background: I recently started taking a focused interest in wine, with Riesling being the varietal I have had easiest access to because of a friend that brought cases of the stuff back from Germany. I'm determined to try as much Riesling as I can get my hands on and learn about it as well; then, perhaps move on to another varietal. I imagine I have a pretty solid understanding of the German Rieslings, with respect to the hierarchy of sweetness and so on (kabinett, spatlese, auslese, etc).
Before I ask my actual question, should someone this "new" to the wine tasting world even be concerned with knowing the difference between auslese and spatlese, trocken and halbtrocken, considering how unexperienced I am?
If so, I wonder: With what I have remaining (there is no more in our stash), how would any of you recommend I go about tasting these wines to try and get a real feeling of how they vary? I have:
2000 Jahrgangs-Sekt Trocken (Bernard-Massard)
2002 Alfred Eigelshoven Halbtrocken (Briedeler-Weiserberg)
2001 Peter Jos. Hauth Auslese (Bernkasteler-Badstube)
2002 Weingut-Peter Kropf Spatlese (Bernkastel-Kueser Rosenberg)
2000 Alfred Eigelshoven Hochgewachs (Briedeler-Weiserberg)
2000 Mosel Bacchus (looks generic; was bottled for a wedding)
My main thing is that I will likely never, ever have this variety of Rieslings in my possession at once--much less from these vineyards, so I would like to try and take advantage of this opportunity. I know of at least one "Riesling guy" around here, so any help would be greatly appreciated

NOTE: I've had all of these before, just never made a special effort to discern; not sure if that was clear
