I like the second point I hope it will be similar to GC3.
An early culture point is great and Eyes of Universe got very expensive. I guess it is a good change.
Maybe you could add a culture point to Elon's Lift too. It is very expensive as well.
I tried to get both wonders in my current game but it did not work (not enough manufacturing, credits).
Not sure about exotic resources. Maybe the changes will devalue them too much - and the galactic bazar.
Edit (exotic resources): maybe a mixed approach (just an idea). First level of modules stays the same and additional upgrades get a revamp.
