I incubated my eggs at 97.5, but you can go as low as 96 and some people prefer 96 degrees. If I were to do it again I'd incubate at 97 or 96.5 because I was battling rising temperatures both inside and outside the incubator as they got closer to their due date.
Personally I turned mine every two hours until day 46 starting at 6 AM and ending at 10 PM, but most people only turn their eggs 3-4 times a day it, I just liked going the extra mile hoping it would increase the chances of a chick in each of my two eggs. When turning, you want to turn them 180 degrees back and forth about their long axis.
The eggs rest on their sides, with the pointy end horizontal instead of vertical so picture a rolling pin, rather than flipping the rolling pin end over end you just roll it about it's long axis. I put two pieces of masking tape with an X on one side and an O on the other and used an arrow I cut out of a piece of cardboard to let me know which way to turn them each time.
The weight loss thing is really very simple. The eggs are porous so water leaks out naturally as they incubate, you want the amount of water loss to be between 10 and 15% of the egg's weight by the time they hatch, you manage this by increasing or decreasing the humidity, then weighing them every week, but I have read you can also weigh them every day until you get the humidity just right and they'll lose about a gram per day depending on the weight of the egg and this may be the way to go at first.
The way to set the humidity is to just set a cup of water inside the incubator, you want the humidity to be about 35%, but the only reliable way to tell is to weigh the eggs and see how they're doing as most of the hydrometers out there aren't accurate. It's surface area, not the volume of water that creates the humidity.
