This is my final take on events:
-Sovereign assesses organic life, believes they are 'ripe' for harvesting and contacts the Keepers to open the Citadel.
-The Keepers don't respond. Sovereign doesn't go straight for the Citadel because, as the Reapers have ensured the Citadel is the heart of galactic government, it will undoubtedly be heavily protected. Also, Sovereign won't know it was the Protheans that prevented the Keepers responding, so may believe the current civilization is more dangerous than it is.
-We have to assume that, either due to distance or the fact that they're in hibernation, Sovereign can only communicate with the other Reapers through the Citadel, either through the Keepers or directly. We have to assume this, otherwise we have to wonder why Sovereign didn't just contact the other Reapers at some point over the next few thousand years and tell them to get to the galaxy with FTL speeds - it only takes them a couple of years.
-Sovereign uses several plans to gain access to the Citadel. Firstly (at least in my opinion, there isn't actual proof of this), it uses the Rachni to cause a galactic war, hoping the Citadel fleet will be called away elsewhere or otherwise weakened, allowing Sovereign access to the Citadel directly. Or it could have been a war engineered by Sovereign to assess how powerful the current civilization actually was, and whether ti could risk just heading straight for the Citadel. This is thwarted by the discovery of the Krogan. Secondly, it uses Saren and the Geth to gain access to the Citadel, Saren having learnt about the Conduit. This plan is thwarted by Shepard.
-While Sovereign is attached to the Citadel, it manages to send a signal to wake up the other Reapers but is not there long enough to open up the Relay.
-When the other Reapers wake up, they realise that not only are they thousands of years behind schedule (civilization was 'ripe' thousands of years ago, so they may have advanced much further than anticipated by now), but with Sovereign destroyed the galaxy is now aware of the Reaper threat and may even now be preparing for it using the remains of Sovereign's technology.
-The Reapers make a beeline for the galaxy's back door, the Alpha Relay, through which they can still gain access to the Citadel.
-The Collectors have been, um, collecting samples of every species for a long time, perhaps from before Sovereign attempted to contact the Keepers, in order to determine which species would be suitable candidates for becoming Reapers. When humanity destroys Sovereign, the Collectors are told by Harbinger that humanity worthy and that construction of a Human-Reaper should begin to see if such a Reaper is viable. That way, when the reapers arrive they know whether to harvest more humans or destroy them, and construction of the Reaper takes place in the Galactic Core, away from any conflict.
-While Shepard destroys the Human Reaper Larvae, the Reapers know that such a Reaper is viable and that they need to gain control of Earth as quickly as possible to ensure they can harvest as many humans as possible before any war takes its toll on humanity's population. When the Alpha Relay is lost, the Reapers continue travelling at FTL speeds, eventually ending up at Earth.
This leads to several points of interest. Firstly, civilization has had a couple of extra thousand years to develop than would normally be possible, so perhaps we stand a chance. Secondly, the Reapers have had to travel at their top speed for approaching 3 years - they're going to be low on fuel by the time they arrive.
However, there is one thing that isn't explained. I said we have to assume that Sovereign can only contact the dormant Reapers through the Citadel, either due to the distance or the fact that they were hibernating. However, Harbinger seems able to contact and even control the Collectors over this distance. Perhaps the Collector Base has some kind of quantum-entanglement communications system - the nature of the Reapers' control over the Collectors would require a lot of instantaneous communication. The only other explanation is that whilst in hibernation the Reapers are unable to respond to anything but the strongest of signal,s which would be from the Citadel. This isn't a plothole, but I haven't been able to find a satisfactory way to explain it to myself yet.
Otherwise, I think my outline of events covers pretty much everything, doesn't contradict any lore or story points and explains pretty much everything. The only thing it doesn't explain is the Collector's interest in Shepard, but I imagine we'll find that out in ME3.
