Try and have a variable keeping track of the number of bricks left to destroy and if that number reaches zero you know the player has won the game. Just check this every time a brick is destroyed.
The same goes for lives, however just check it every time the player looses a life. If lives is zero, player lost.
When it comes to removing the brick from the board I guess you have some sort of array or something representing the board of bricks. Just set the coordinate in the array of the brick that was destroyed to null to represent that there is no brick here any more.
