I am on a big bundle and I want to change to normal pay as you go as I rarely use my phone. Can anyone tell me if this is possible or do I need to get a new sim? (If I need a new sim, is it possible to keep my number if I am on 02 and I get an O2 sim?)

Not possible with O2 unfortunately.
giffgaff is your best choice, or Tesco mobile, but you'll need a new sim from one of those and you'll need your PAC from O2 to keep your number.
