In my experience:
1. There is an increased risk of soft tissue damage and post-op sensitivity with self administration but both are reversible problems.
2.True. That's why it's "self-administered".
3.True. Informed consent is an obvious requirement before any treatment is rendered.
4. True. 1 1/2 hours is double the time required though.
Whitening by dentist is certainly faster, safer, more predictable and more convenient. If you are willing to pay for these things and want them, then the choice is clear. Go to a dentist for whitening.
