Are you curing, or brining? There is a HUGE difference between the two -- in time, process, and food safety. If you are not using curing salts, then you are only brining and can move to the next step of cooking any time you wish within a few hours to a few days (as long as it is refrigerated the whole time).
Curing meats is another thing entirely and not done willy-nilly. This process is much more precise and should only be attempted with close supervision/advice from someone who is experienced. It's not difficult; it's just SUPER important to get it right.
DO NOT cold smoke unless properly cured. You can make people sick or worse. You can hot smoke (cook) it any time you want.
Nitrites are used to kill bacteria, especially botulism. It has nothing to do with trichinosis.
Don't listen to the alarmists here Ben, they're misinformed. If you're using factory raised pork that hasn't been frozen, trichinosis may be an extremely unlikey concern, but with farm raised pork, salt curing ham is safe and easy. The meat is preserved through dehydration.
I haven't made country ham, but I did make a prosciutto style ham last time I butchered hogs. Ideally, you want a draining board to set it on, but lacking that, I kept it on a sheet pan in the fridge, with some weight on top. Every few days, I would drain the liquid, turn the ham over, and add more salt as needed. After about a month of that, it was no longer losing water and was ready to hang. After rinsing the salt off the ham, I covered it in lard and black pepper. Not wanting to spend a bunch on that much cheesecloth, I wrapped the ham in brown paper and hung it in my cellar for about a year. It got moldy and had a few bugs on the outside. I was a little nervous when I finally decided to cut it down, but after cutting away the outer layer, I found delicious perfectly cured prosciutto.
Making country ham is similar, except as you know, you use brown sugar in the cure and smoke it at some point. There is quite a bit of information on it online if you look around a little bit.
In answer to your question, you're ready to move to the next step when the hams are longer losing liquid.
You are the misinformed amateur who will get someone sick or dead with your advice. Your focus on trichinosis shows your ignorance. Satph has is right: botulism and other bacterial contamination is the key concern. Methods you describe are incredibly dangerous in the hands of an amateur. One attempt at making something does not make you an expert. Just because you got lucky doesn't mean you should put someone else at risk. Your advice flies in the face of meat curing wisdom and safety.
OP, if you don't want nitrates/nitrites, fine. Just follow satph's advice and hot smoke and get the meat through the 40-140F in 4 hours or less, and your family and friends will be safe.
If you are still unsure about who to believe, please do some more homework and get some solid advice from some place other than a brewing forum -- preferrably from someone who has a lot of experience curing meats. Books and butchers and chefs are a good places to start.
