I think the easiest way to trade ETH is to deposit on poloniex.
No matter with personal document and other stuff.
Have fun
We even can't open wallet, command line is terrible, and there are some other errors when I try to run ETH, kraken is a good choice if it works safely
If you want a wallet with GUI you can use alethzero. It is at the beginning... But you. Can import IPO json wallet file, you can check your balance and do transations.
