I've never been shy about using levers to get a tire back on (plastic ones, so I don't mar the rim, and they slide a bit better on the tube as well). It's rare enough that I trap the tube, that it's totally worth it to me to go ahead and use levers when a tire is being balky. All you have to do is be careful, and check the bead carefully both before you air the tire and after you've got a good amount of pressure in the tire. I've never holed a tube during installation with plastic levers.
I think lubricating the tube with corn starch or baby powder, besides letting it slide freely inside the tire, helps avoid pinching during installation also.
