As I understand the dying part was supposed to be a DLC for ME1 that never came out.They wanted to throw it out 1-2 months prior to ME2 as a bridge and a cliffhanger except they didn't and they couldn't just up and rewrite the story of why he got affiliated with Cerberus.
As for Cerberus being too omnipotent to have rogue cells, you could go revisit Jack's storyline and how she came to be.
The ending is actually pretty important and it ends like that for a reason.The whole deal of the reapers is that they leave ready technology and allow other races to use it without them fully understanding it(keepers do all the work).Then they go and kill them every 50000 years.If you pick up the reaper technology you effectively build on top of them thus probably repeating the cycle.Legion has an awesome comment after the suicide mission (paraphrasing) "you decided to allow yourself to develop without the aid of reaper technology thus creating a future created by mankind rather than given to them".
The traps were actually interesting never thought about them.That mission usually pops up when I'm more interested in my teammates rather than the main plotline so I kinda miss the idea.
