They explained how Valkyrie got her powers later on in the New Ultimates. Thor could just be because he is no longer human since he got his full god powers back (he doesn't use the harness) but they fixed it later on by Tony donating a large amount to any charity that Thor chooses if Thor talks normally again.

No one fully recovers of the death of a loved one, plus he could become an alcoholic because of his sex life being revealed to people via dvd/video.

They explained the Venom situation and how the Ultimates knew about it in the Symbiote War arc what was made after Ultimates 3 but based before it.

Doctor Doom appeared before Ultimates 3 since he appeared in Ultimate Power what happened before it. Hawkeye simply wants to be with his family and haven't gotten over the death of his family.
