Can you put DDR3 1333 instead of 1066?

Both memory modules should work and operate at 1066 MHz. If properly supported, the modules will operate in dual-channel mode, but both modules will be limited to the slower one, which is unlikely to be noticeable. There should not be any significant problems in terms of system performance or stability.

Can I use 1333MHz and 1066MHz RAM together?

No, the correct answer is that it does not matter. You can mix RAM of both speeds (1066/1333). The system will automatically use the slower speed, but there is no risk of system crashes. And no, 1333MHz RAM will not be recognized in a 2009 iMac, but 1066MHz in the 2010 is just fine.

How much RAM can a 2010 MacBook Pro hold?

Can I use 1600MHz RAM with 1333mHz RAM?

The compatibility of the ram depends more on your motherboard than your cpu. If your motherboard supports the 1600mHz, then it is likely that the g3258 will also. However, the cpu spec sheet says that it only supports up to 1333mHz, so if you use 1600mHz sticks it may downclock them to 1333mHz.

Can I use 1333MHz and 1600MHz RAM together?

You can, both sticks will run at 1333MHz. As long as your motherboard supports more than 8gb of RAM, which most of them do.
