Answer 1

UPDATE: IT WAS SUPPOSED TO WORK, BUT IT DOES NOT

Seems like there is |See Doc Reference|

pop(opts) takes one parameter of type object

so

to go one step back

this.nav.pop({
    thing1: data1,
    thing2: data2
});

and to go to a specific view in the history stack

this.nav.popTo(SecondPage, {
    thing1: data1,
    thing2: data2
});

and to go to root of the stack

this.nav.popToRoot({
    thing1: data1,
    thing2: data2
});

To retrieve the params (I guess this should work. untested!)

export class SecondPage{
 constructor(params: NavParams){
   this.params = params;

   console.log(this.params.get('thing1'));
 }
}

Answer 2

Currently, I believe that there is no way of accomplishing this.

There is a Github issue for it though, that has got some great discussion on it by the Ionic core team. It sounds like they have added it to the Ionic 2 roadmap, too! The Github issue also has some proposed work-arounds, such as adding the ParentPage to the NavParams going to the ChildPage, but it is all quite a bit hacky.
