Holes in the plastic will defeat the purpose of a vapor barrier. The idea is to prevent, or reduce, migration of warm moist air to the cold space above the insulation where the moisture will condense.
As for putting up plastic, many hands make light work.
Good luck

This is for my walls and I would patch the air holes when I was done packing the cellulose so that the barrier would be intakes. They use a cover the let's the air escaped when pros do it but I don't have the funds for that much less hiring it out.

Depending on your climate zone plastic sheeting may be a really bad idea. If you are in a hot - humid climate you do not want anything on the inside that could be a vapor barrier. Not even vinyl wallpaper. Especially bad if the interior is air conditioned.
