This one is pretty easy to answer :)
If you leave the Opera district around 6 AM, it won't take you more than 30-40 minutes to reach CDG airport (unless there is a big incident). Trafic jam starts around 7:15-7:30 AM in this direction. So if you arrive on the highway before that, you are pretty safe!
How difficult it will be to find an Uber around 6 AM? Well, I think it should be ok. Done it several times without any issue. If you can't find one, you can take a taxi which will costs you around 60-70 β¬.
Then for the fare, it will be 45 β¬, not less, not more, if you book with Uber X.

In my city you can book an Uber in advance using a 15 minute time window.
This feature is called 'Schedule a Ride' and was introduced in the last couple of months.
You can request an Uber up to 30 days in advance now, perfect for those early airport runs.
Check to see if this feature exists in Paris. My city is not listed on the Uber site so maybe Paris is the same?

Absent any traffic, it takes just over half an hour to get from your location to the airport. With morning traffic, it could take up to an hour. 75 minutes is definitely an overestimation.
Since Uber is "on demand", it can be difficult to plan too much in advance. Still, 10 minutes ought to be enough time for you to summon a car. If you are concerned about this, you can check the app when you get up to get an idea of how far away most cars are.
It should cost you somewhere in range of 40-65β¬.
(As mentioned in your other question, taking the bus is also an easy and cheap option based on your location.)

Since you are in an hotel, ask them to make arrangements with a taxi to pick you up so you arrive at the airport at the appropriate time.
They are used to do this.
Google maps says it should take about 35 minutes on a Monday morning.
There is usually a fixed price from the Center of Paris to the airport; so you know in advance how much it will cost you (50 euros from the Rive Droite and 55 euros from the Rive Gauche).
