Mine on CPU and GPU at the same time

Hello friends

I am newbie in mining. I have few machines with dual XEON E5-2670 (8 core, 16 threads), and they also have got dual GTX780 each.

Can I mine on CPUs and on Cards at the same time?

I also have another question

I've downloaded and compiled the wallet, generated the Taddress.

Then I went to Zmine (it is pool, as I understand), downloaded and compiles a NiceHash miner and launched it with the Taddress which I've generated later in my wallet.
All payouts will go on that address. Am I right?
