Im glad to see that you caved! lol. I honestly think that the more you do and the more you worry, the more issues you have or cause. I am not familiar with that incubator other than seeing it in the stores. That being said, they look practically the same as the LG. IMO, these are great incubators to learn how to hatch in because it seems if you can be successful with these, you can hatch with anything. You can NOT beat yourself up for failed hatches. Its part of learning.
Before I would actually put eggs in the incubator I would do several different trial runs. First I would calibrate the thermometer and hygrometer. If you can pop out the hygrometer, it will be easy to calibrate. I take a medicine cup and put salt in it. then add enough water to make it the consistency of wet sand. If you were able to picck up the salt in your hand you should be able to form it, but not have water run out. then place this medicine cup and hygrometer in a plastic bag. Leave it for 8 plus hrs. the hygrometer should read 75%. if it doesnt then you need to "calibrate" it. example; if it read 72% then you need to add 3% to all your readings in the incubator, and likewise if it read 85%, you need to subtract 10% each time you read the hygrometer.
To calibrate your thermometer, i just get several different ones that all measure the same and use them. There is a way with crushed ice and water, but not familiar with this method.
I like to use 2 or more thermometers. a great one I use is this:

I like this one due to the small probe. I can easily slip it into the vent holes on top or make a small dent between the lid and base and slide it in there. I typically just leave it hanging through the top vent holes.
Now, as mentioned above, i would do several different trials BEFORE putting egg in there to help eliminate headaches. First run it with all vents open, egg turn in and running. Figure out how to get the correct temps (99.5F) and humidity (i dry incubate and incubate around 30%. i dont like it lower than 25% or higher than 35%. I try to maintain the 30%). Once you successfully acheive this, then turn off the turner and take it out. Verify the temp does not drop as the turner does have a motor, thus creating heat. Once that is verified, move onto increasing humidity. I try for 55% humidity at lockdown. Once they start hatching it can drastically increase. mine got up to 95% last night and endedd up causing a chick to become stuck in the egg and die after it pipped. So just keep an eye out when they start hatching.
Once you figure out what you need to do to acheive correct temps and humidity during incubation and lockdown, then I would add the eggs. My first hatch, I calibrated the incubator for the first 18 days, then I had no idea how to get the humidity correct and was constantly messing with it to get it correct. this made me more nervous than necessary and more of a headache.
For lockdown and humidity, I have found that with both vents open, I can place a rubbermaid food storage container that is about 6" long x 4" wide x 2" tall with a sponge about the same size filled with water puts me at the correct %. I dont use the wells in the bottom tray as i founnd theem harder to keep filled. This way, I just fished a piece of 1/4" tubing through the lid into the container and under the sponge to keep it in place. I think use a 60cc syringe and fill it through the tubing that is sticking out the top. I will try to get pictures to help explain. If you are using the bottom channels, you could probably due the same thing with the tubing.
On top of the wire floor, I put down rubber shelf liner. this helps keep most of the poop and egg pieces on the top and not on the styrofoam. the chicks are able too stand on it better as well. Also, incubating in a room that has a very stable temp will give you the best results. also wait several hours after making a temp adjustment before making any more. With the LG, the temp control knob is VERY sensitive. I found shining a flashlight on it makes it easier to see when you are turning it. I barely turn mine and it willl lower the temp by a degree or two.
I cant recall anything else off the top of my head so feel free to ask if I have missed something.
I would give this one a try. if it doesnt work for you then you could always sell it on craigslist. Unless you want to get another incubator to hatch in, thenn yes the chicks will also hatch in this incubator. after the majority hatch and are dried out, then move them to a brooder.
Yes, do not wash the eggs. I also do not incubate heavily soiled eggs.
