to tell u the truth a cocker trim is a cocker trim unless u have her shaved off which i wouldnt personaly do esp as she sounds like a dream to groom.
right most cocker coats r hand stripped u will have to ask the groomer if they do it not all will this is where the old dead coat is pulled out they go all fluffy when this needs doing its harder to see on a puppy coat as they r all fluff but if u lighty pluck the hair and it comes out easy it sholdnt hurt her at all if it dose its not ready yet , so her head top of ears neck and all down her back should be stripped if this is done when she is an adult this wont need to be done as much and she will keep looking nicer for longer which is good, then she will be bathed then dryed she should lay nice and flat after all the rubbish is stripped a way then her feet will be trimmed and thinned to make them look like little neat round cat feet and all of her feathering with be triimed in to shape follwing the lay of the coat she will look fab

if u hand strip her coat will keep a butiful glossy healthy shine to it where as if it was shaved after a few time it will go dull and lifeless in most cases and also the coat will turn wooly and they will look a mess in 6 weeks unlike the hand stripping
if u hav her clipped on the back they can shave her all off or shave where she would be tripped and then have her feathering trimmed up
but handstripping is the way to go it really is
its up to u then how short u have her feathering really most pets have it about 2 or so inches long but its really up to u
i hope this has helped a little im a bit tired so i hope it makes some sence
