[development] JQuery heads... I would love some assistance.

I've got an outstanding request for enable jquery on imagefield. I was wondering if there were any experience JQuery folk out there who could help me. I figure what I need is much like what is in upload.module. I would appreciate help identifying how to target the wrapper around the imagefield and how to get the button to trigger a request back to a js callback in imagefields. I also need to figure out the addition context I need to pass back, like field_name and how to cope with having multiple upload fields on one page which upload.module doesn't. If you're interested please email me directly.
