Where do I find their quotes, how do I follow them, do they have symbols like stocks? Is there a future for every stock or is it something for the whole market?
Your data provider may or may not provide futures data depending on the your setup. The leading indicators Magna and others refer to are the S&P 500 (SP) and the Nasdaq 100 (ND) large futures contracts. These are based, of course, on the indexes of the same name, also referred to as "the cash" indexes. There is an open-outcry pit where the large contract is traded and an electronic session (Globex), which runs concurrently and overnight. The electronic market trades a much smaller version of the larger contract. These symbols are ES and NQ. All four are traded at the Chicago Mercantile Exchange. The Merc is a good place to start looking for info.

Futures use a letter to identify each month. You need only be concerned with H=March, M=June, U=Sept., Z=Dec. Thus, each contract is identified in this manner: SPU01 where U is the month and 01 is the last two digits of the year. Not all providers use the same order, so you may find that it is SP01U.
Contracts have a limited lifespan. At any given time more than one contract is available to trade. Generally, the front or spot month is the most active month. This is the one you would trade, as it is the most liquid. The front month is the closest to expiration. Contracts expire on the third Friday of the month indicated in the contracts symbol. Prior to expiration, the next month behind the front month becomes the most active as traders abandon the old contract a week or so before the official date.
Sometime, in the near future, Single Stock Futures will be available. The margin and contract specifications have yet to be completely sorted out. But I'm working on it...
