hi there, sorry about the late reply, but it would see that the other members have managed to get through most of your queries.
the most important one for you is. yes, on termination and cancellation of your labour card you will be banned (labour) for six months. as you have not worked out a full year under your current employers sponsorship you cannot transfer either.
you are correct in assuming that one of the freezones will be able to offer you an oppertunity without the ban being implimented. off the top of my head there are about 15 "freezones" in the uae - a number of which have already been mentioned in the postings above. have a look at this link:

there are a few more zones currently under construction including the dubai flower centre, the business bay development and silicon oasis... although i would think you have to act now. pleanty of people working in the freezones make the 60 day tour to the border and back.
on cancellation of your residency visa you have 30 days to exit the country before you are considered illegal - trying to exit after this will result in you being taken into custody and fined for every day over your cut-off point. this means, once cancelled - take a trip to oman, do the in and out thing, that will give you two months to try and sort things out in one of the fz's.
i can't comment about the banking issue, but would assume that numerous other people have crossed from a normal dubai labour contract to a fz contract - i hardly see the jails bursting at the seams. it may be worth contacting the bank and telling them that you are considering changing jobs to the fz, and see what thier response is. i have a meeting with a rep from one of the banks tomorrow and will try and find out from her.
working in a fz still gives you residency status - if they do the paperwork for you, hence you'd be able to drive you car around and have it re-registered. the only problem i could see is that you are able to find a job in one of the fz's, but they won't provide you with residency and require you do do regular visa runs (this happens a lot as well); this would cause an issue with registration.
trust this helps ...
