You are semi accurate. Dont feel discouraged. You have normal questions.
Opening the lid every so often is indeed an adequate method for allowing gas exchange. However, I placed the aquarium air pump in the center water pan(via Damons example) as an automatic means for introducing osygen into the incubator on a costant basis, elminating the necessity for occasional opening of the incubator to achieve the same results. The air pump is also supposed to help raise the humidity.
The fans are important because they mix the air and humidity which help to provide even thermal (temperature) distribution.
The thing with fans in an incubator is that you dont ever want an air current blowing directly over eggs as this will be a factor in drying them out. The plaement of fans depends on the size of the enlosure and the location of the heat source.
Typically heat rises right? So if you have a tall enclosure you will probably want to place fans facing perpendicular to each other in a vertical fashion (one at the top and one on the bottom). My fans are located horizontally because my enclosure is shallower and the fans are placed in between the heated water pans and the egg boxes to circulate the rising heated air to avoid hot spots. This allows the temparature in the egg boxes to rise evenly.
I rambled but I hope this is helpfull.
