There was quite a lot of foreshadowing in ME2. How about all that business with Dark Energy that everyone and their mother is suddenly interested in? Like with Haestrom's sun. There's no way that was thrown in there the way it was unless it has some major impact on ME3. What about the Quarians, with their Admiralty split on how to handle the Geth? I betcha we'll see Xen again in some form in ME3. Or the Geth schism and Legion's loyalty? That could definitely have major consequences in ME3. Or the genophage, which was explored much more explicitly this time around. We confirmed that the Rachni were indoctrinated in ME2, with the Rachni messenger, meaning we can count on their aid against the Reapers.
The setup for ME3 wasn't in the Collector missions. We learned much more useful information in recruitment and loyalty missions. I'm inclined to say that the Collector missions really were more of a background story. Although learning the Collectors' plans to build a Reaper (no matter how contrived that is) is valuable information. Now we can learn more about the Reapers from the base or its wreckage. This is not insignificant.
Really, Lord of the Rings is more of the exception than the rule when it comes to trilogies. A more appropriate analogy would be to compare it to the original Star Wars trilogy (as much as I dislike Star Wars). The comparsion of ME2 to The Empire Strikes Back is striking.
I was actually trying to avoid using TESB as a comparison, but since you prefer TESB to TT let's go with that

The only loyalty missions that foreshadow anything are Tali, MOrdin Grunt and Legion (4 our of 12<_<) so those were good. And that brings us back to the CB and the RQ, and more than afew people wiped the Rachni out back in ME1 and more than a few blew the CB base however, so you can't completely count those variables because not everyone 'knows' that or has the CB or both.
We already knew that the Rachni had been indoctrinated when you first met the Queen in ME1, so that wasn't new. The Collector missions weren't all that illuminating really, a - we know the Reapers re-puposed the Protheans into Collectors since their DNA wasn't felt to be 'up to snuff,' B- they were building a baby-Reaper, the Collector Ship only told you that they were after massive amounts of humans, C - the SM tells you the 'why'. Also, since you mentined Haestrom, you should also be aware of Solveig which is prematurely turning into a Red Giant due to the same causes of DE.
But the overall story itself didn't move forward with the Reapers to find ways to try and stop them, it didn't even feel like anything had changed that much. NOt when I was spending 99% of my time recruiting and then their LM because other than the Krogan with Wrex, hopefully the Quarians/Geth (No guarantee that both won't be dead), and the RQ our list of allies is painfully short since we can't count on the Council Races to help us out at this point and we still lack seriuos tech to halt/stop the Reapers...
