Pop bumpers are a pain to remove, do you REALLY need to? You will have to unsolder the lamp
flippers are removed from under the playfield (unless it is a Zac), look at the flipper mech, it will be obvious (and simple)
and if you are giving the playfield a good clean then you should look at also doing a flipper rebuild
roto targets, not sure
but if you have a look at Ninos restoration threads you will find he rearly unsolders anything
soleniods and switches are unbolted from the assembly and left in place
