You don't need margin for options so long as your transactions fall under level 1 or 2. All that means is you can't lose more than you have. So buying contracts or selling contracts you own would be examples as would covered transactions.
You do need to execute a separate agreement to trade them. Call your brokerage and ask.
Options are fun. Just don't get carried away. When you're wrong you're usually really wrong investing that way.
I'd also avoid currencies. I prefer more volatile plays. Pick some really volatile stocks like Netflix as an example and play it.
