Seats at the PNC Bank Art Center(NJ)?

I want to go see the My Chemical Romance and Blink 182 concert there. However, the tickets are a little pricey, but i want to really see the show and see the bands. If i bought lawn tickets, would i really be able to see the bands or just hear them? This is my first concert and i'm a HUGE fan, so should i just get a seat and enjoy the concert. If i did get a seat in the orchestra, you i kind of see the bands? Thanks!
