How to send tokens to MetaMask ?

[creativus]

I have ERC-20 tokens SUB and NAS on exchanges and I want to send them to MetaMask ?

Do I need some ethereum in both the exchanges and MetaMask for the transfer to happen without a problem ?

While sending tokens you need ethereum to cover for gas cost right ? If I do not want to leave anything how do I calculate how much ethereum to leave to cover the gas cost ?

I think I also got my ether wallet but somehow metamask seemed better to me. I have checked instructions on how to send tokens out of metamask using myetherwallet though I didn't try it. It seems you just open metamask and then you access your wallet by choosing MetaMask / Mist on myetherwallet.com to send tokens out.

Right now all my tokens are on exchanges, none is in a wallet. I want to purchase some ethereum with my tokens and then send them all to my MetaMask wallet.

My own challenge is not with transfer of token but am looking out on how to connect or merge my MEW with metamask so that i can be monitoring both at the same time but i cant find any where to get details on how to achieve this.
