I don't think you are gonna have it very long once you start smoking it but here is my plan for cheese and it was taught to me by Mrs Scar who learned it as an employee of Hickory Farms.
We vac seal it for at least 2 weeks to allow it to age with the smoke then use it as needed. Once opened we use it fairly quickly but we have forgotten it in the fridge a couple of times and it has started to get some mold on it - when that happens we clean off the mold and refill the hole were the mold was reseal the cheese by using some plastic wrap to help keep the air out. Then into a baggie and suck the air out - at that point you need to use it fairly soon or the mold comes back pretty quick.
Hope this helps - we have had some in the fridge for as long as 6 months with no problems
