400% is the best to farm levels for your character and your guns, I think it take 5 runs to max the level without XP boost items. It also gives you modules to combine and then deconstructs (for more modules, then for kuiper). You should do all 4 infiltrations daily because each one gives 1.5 million gold (and money is what you will be starved for toward the end of the game as you slowly level everything up).
For Catalyst Blueprints, do all the Colossus you can get, public. Look at which ones you have amorphous materials for and run it until you're out of them, then move to the next one.
