Definitely. Listen to the poster above, good advice.
I would also recommend you get a basic, if not thorough understanding of Micro and Macro economics. It is essintial you understand how supply and demand curves work if trading futures. Understand situations like:
"If country X is heavily reliant on oil from country Y, then country' Y's oil production is cut by half, what does country X do for oil?"
There are a number of conclusions that can arrise from this situation, but perhaps a common one would be, country X would have to acquire oil from another country. This would increase market supply, and perhaps if the quantity was large enough it could very well create a market-price flucuation. Then you have to ask yourself, when do you see price flucuation? Is it immediate, is it long-term, also how long do you see this increase and/or decrease for, is it permanent, or just for a few months? All types of questions you have to ask yourself when getting involved with Forex or Futures
This senario, is only meant for example purposes and is not meant for any type of investment advice or recommendation(s). All Im saying is understand the the effects of supply and demand of the futures you plan to trade. Also understand that some commodities, effect other commodities, often times there are direct correlations between them.
Also, definitely do what SpearPoint said, and understand what futures contracts are, forward contracts, assignable contracts, short-date forward contracts, all that sort of stuff, which as SpearPoint said will be in a traiing course, specific to futures.
Hope that helps as well.

I would start by studying one of the many trading courses, specific to the Futures and commodities markets. Get one for a raw beginner. You need to understand what a futures contract is, how those markets work, and what they are for, as well as proper funding. You also need to understand what leverage is, and that you can lose substantially more than you put up because of the leverage used.
Futures and Commodities are very dangerous if you are not properly educated.
