From the official Mafia Wars blog:
One of the ways you'll be able to rob is from the Fight Tab which will give you random targets. From there, you'll be presented with a grid containing robbable properties that are color-coded to show you the level of difficulty in trying to rob that property. The size of the properties will determine how much effort will be required to rob. Going after the bigger properties will require higher stamina cost and more mafia – but the greater risk will yield the greater reward. Finish the entire grid, and you'll receive bonus expand a chance for the rare robbing collection item! Robbing will have a 10-level mastery bar for you to conquer, and every successful heist will move the bar up. Earn cool new titles and earn higher bonus exp with higher mastery levels.
In addition, you will be able to rob a player from their profile page. If you have a beef with someone in particular and choose to rob them, you'll be shown their list of their robbable properties and the stamina cost needed to rob them. Here, you'll have to proceed at your own risk - the properties for a specific target won't be color-coded to show the degree of difficulty to rob. Do keep in mind that with this method, you won't get a shot to bank the rare robbing collection, and robbing from the profile page won't increase your mastery.
When you get robbed, you'll be able to see which of your properties were hit. If you roll your mouse over the robbed property, you can find out who robbed you. Click on your robber's name to get to their profile page, where you can choose to alert your mafia or retaliate directly. If you remember to keep a close eye on your properties, you can prevent being robbed. Just watch for when the properties are ready to collect from, and cash them out soon to stop looters in their tracks!
Keep playing Mafia Wars and be on the lookout for when we finally unveil robbing. Start out as an apprentice burglar and try to work your way up to Grand Master Thief, and grab exclusive collection items along the way. Think you've got what it takes to face this new challenge? Stick around and find out!

Robbing is good, and by virtue of not robbing, you're missing out.
Why win robbing fights?
1. Experience
When you win, robbing pays out good Experience per stamina point. A successful robbery generally pays out 2 or more Experience per stamina point spent, on top of the bonus for clearing the grid (+10 Experience for each successful robbery). So, for successfully robbing a flophouse, you not only get the 4 or 5 Experience for winning, but also +10 bonus Experience on your clear! That's a 7:1 Experience:Stamina ratio. Even if you skip grid clears when there are a lot of casinos, its still great Experience per point spent, especially as your mastery increases.
2. Loot
Clearing a grid in robbing can result in the the dropping of a diamond from the Stolen Diamonds robbing collection. The diamond collection is great for two reasons. First off, it's valuable. Each diamond piece is currently comparable to a lotto set piece in worth.
Side note: I think the Diamond set will plummet in value very quickly fast, at least compared to the lotto set. It can only be vaulted once and there is no rate-limiter on the rate at which it enters the game (the lotto for example only happens 1x per week - but people rob around the clock). Trade off any extra pieces fast - don't hold onto them for long periods of time.
Another reason why the Stolen Diamond collection is good is that because in this case, wealth begets wealth. Since the diamond collection improves your chances of winning robberies, you will earn more Experience levels, loot, and ultimately be able to rob more often. Additionally, since you will be winning more robberies, you will be earning more experience.
In theory, a well-equipped, high stamina, high attack account with the Stolen Diamond collection vaulted could be effectively used to 'farm' diamond collections.
3. Robbing Mastery
As you win robberies, you get more mastery. This goes hand in hand with reason 1, as by gaining more mastery, you can earn more experience. By earning more experience, you can level up more often, and end up winning more robberies, so on and so forth.
All of these three factors are synergistic and by virtue of winning a lot of robberies, your Mafia Wars account certainly stands to profit. Now, we just need to look at how to win robberies! Good Luck.
