I would not mix extraction and advanced production on the same planets. Generally, you want to have dedicated extraction planets to extract the maximum possible amount of material from the planets and dedicated factory worlds to setup the maximum possible number of processing facilities.
If you want some inspiration: I put the following setup times 2 on my extraction planet and process the T0 into T1.
The T1 goes on to the first factory planet with the following setup to be turned into T2. This factory planet can process 16 T1 materials. here you have 2 input launch pads that make importing materials easy and 1 output launchpad. This provides enough storage for about 2 days of production.
And that goes on the third factory planet to be turned into T3.
