The end of the passage states "the potentially healthful effects of moderate wine intake may derive from the concentration of certain natural compounds found in grapes." That seems more like a hypothesis than anything, and the fact that this study was the "first step" suggests that there nothing definitive has been proven about grapes and heart disease. In addition, even if something about grapes definitely reduced the risk of heart disease, it doesn't mean that apples or plums might not have the same effect. In this context, "unlikely" seems way too strong; the effects of apples and wines are merely "unknown" or "unexplored."
Good question. Since we're looking for the answer the author is most likely to agree with, that wiggle room is acceptable.

I took this to mean that although beer and spirits have alcohol as the exclusive active ingredient, wine is different. The next paragraph talks about alcohol having conclusively negative effects, so if beer and spirits only have alcohol, why bother studying their potential healthful effects?
The text you're referring to suggests that the apparently incorrect assumption led those scientists to feel there's no reason to study the effect of wine as separate from other alcoholic beverages, which is different than saying that we shouldn't study the effects of any of the beverages. Instead, it's saying that we shouldn't lump them together.
As for your savvy point about the second paragraph suggesting there's no positive effects of alcohol, here we'd want to see a more soft point from the author -- there's little chance that other types of alcohol... -- and instead we get a very firm statement that we should never study these things. Just because something is believed doesn't mean we shouldn't study it.
