My suggestion is to look toward the Pro's!
There is two excellent tutorials here. Pops which is a brine and BearCarvers which is a rub.
Here is what I understand, max heat allowable is approx. 140 degrees. The warmer the bacon the better the smoke holds on, but you don't want to "Cook" it or render the fat. So from what I have seen some do cold smoke with a smoke generator the entire smoke. Some of the more seasoned veterans do extended smokes gradually increasing the temp from 100 to approx. 140 carefully watching to not render the bacon. Some small amounts of weight loss are generally given to loss of water from curing. Less than 5% seems acceptable.
Cold smoking can but doesn't require a cooling medium like ice. More normally its achieved by just using a smoke generator with no additional heat from the smoker.
If you still have questions and don't we all, I would suggest you read either:
Craigs Tutorial (Pops Brine)
These guys are ahead of the curve on makin bacon.
This was my first attempt at making bacon last year. Some good starting notes at the end, or I thought so anyway.
BTW this was my last batch last year, I had never cured before last year. These guys are really great!
