Why didn't they just wish Dr. Gero into the hyperbolic time chamber and destroy the door when Trunks comes back in time to warn them?
I don't think they knew that Dr.Gero was alive, it wasn't implicitly stated. It was only stated that he created 2 Androids who came to life and wrecked havoc.
My only gripe is why didn't Vegeta continue training in the hyperbolic time chamber versus the gravity training ? He got immensely powerful multiplying is power level like 10 fold in just 1 day (Earth time). If I were Vegeta I would have spent a week in there training, the amount of Zenkai boosts Vegeta would have gotten from the harsh climate both physically and psychologically would have pushed him beyond SSJ2 to SSJ3. I would have taken younger Trunks in there with me and gone all out.
The issue with Vegeta maaaannn, he never asked for help, whereas Goku always did. That's why Goku was able to go so much further and why it took Vegeta so long to catch up. Sure he was still second strongest but he could have been on Goku's level in DBZ towards the end if he utilized help. I must say tho, for MOST of the sagas save for the Buu saga Vegeta was practically neck and neck with Goku and when Goku was ahead it was only by a small margin.
