To be frank, I never saw the Collector plot as being central to ME2.
ME2 is about fleshing out the world, showing the sides of it that were only mentioned in passing in ME1, during the frantic race against the clock - and planting the seeds for ME3. It's the calm between two storms. ME2 also, more than ME1, shows us the lives of the ordinary, unimportant denizens of the galaxy.
Pretty much this.
ME1 shows us all the good stuff of the galaxy - the Council, the Citadel. Things like the Genophage and the Quarian-Geth war are little more than codex entries. The Reapers are given no motive and are essentially evil 'just because'.
ME2 then expands on the darker side of the galaxy. Cerberus, Omega, the Terminus systems, the Krogan, the Quarian-Geth war, the Genophage. It also greatly expands on the villains. The Geth are no longer generic evil robots - they now have factions, we understand their 'society' and way of thinking much more. The Reapers are no longer just evil for the sake of it - we know have an understanding of their reasonings and their motives.
Both games merely explore the ME universe - the Reapers don't actually play a large role in either of them. ME1 is about you chasing down a rogue Spectre and his army of Geth - Sovereign doesn't come into play until near the end. Likewise, ME2 is about assembling a team to fight the Collectors but actually fighting the Reapers - through the Collectors - only happens every now and again.
In both games the Reapers are just a background threat occasionally brought foward for a bit.
ME1 paints us a broad overview of the ME universe.
ME2 goes into the detail and the nitty-gritty much more.
However, both games are merely building up to the galactic war. Niehter of them actually that essential - stopping Sovereign merely delayed the Reapers by a few years, and destroying the Human Reaper just meant that the Reapers' plans for humanity were set back. In the grand scheme of things, we don't actually achieve all that much in either game. Really, all we've done is flesh out the universe and set up some of the pieces. The story will mean so much more to those of us that have experienced the journey leading to ME3, but you don't to experience the journey to enjoy the destination - the destination here being the galactic war which was always going to be the focal point of this series and story.
But if you want a reason as to why ME2 matters think of it this way - without ME2 we would have no clue as to what the Reapers' motives are. Plus, we also prevented (or perhaps only delayed) the construction of a new Reaper, meaning that the Reapers will have to harvest Earth as opposed to just destroying it straight away. In ME2 we basically bought some time for humanity and the galaxy, which is pretty much what we did in ME1.
