For number 1, you should also consider how much of what you attempting to aggregate is already being done.
Movie recommendations? That seems like it would require you to tell the software movies that you liked. The problem is: Who wants to do this on a site that doesn't let you do anything else with movies? People are more than happy to tell Amazon what movies they like (by buying them) or Netflix (by renting them), but why would they take the time to tell your application what movies they like just so they can get recommendations which they could have gotten at Netflix, which they are going to use to go to Netflix and rent anyway.
Email lookups? Beating Gmail is very unlikely. I don't care about instant notification of email. I care about being able to manage email in a sensible and streamlined way. Again, your application it sounds would just tell me I had emails so I could go to Gmail and manage them... Well, since I'm going to Gmail anyway, what has using your application helped with?
Aside from that, I do not think many people will actually pay a yearly subscription fee for such a service. People online don't like paying for anything.
I'm not trying to bash the idea. I'm just saying it needs to do something DIFFERENT.
