Hi SRosen,

Your question is equivalent to this (leaving forex out for the time being, since it is a completely different asset class):
"I have no prior experience of mechanical vehicles, which do you suggest I start to learn:
a. Bicycle (Equities)
b. Motorized Biclycle a.k.a Motorcycle (Futures)
c. Helicopter (Options)
"
The difference between an option and a cash equity is as dramatic as the illustration above, just as a helicopter moves about in 3D space, and a bicycle moves in 2D space, an equity (and future) are instruments with linear (1D) risk, whereas options involve multi dimensional (actually 5 dimensions) risk. The difference is that stark.
Currencies are a different beast all together. Spot currencies are similar to cash equities, once you get your head around the fact that you are both short and long in the same trade.
Overall my recommendation would be to start with cash equities (any skills you pick up there, risk management, order placement, positioning etc), would be largely transferable to other markets. To even contemplate trading derivatives before having a grip on the cash underlying, well ..
