Chess move notations

Can somebody please explain the standard "move" notation that I see all over this sight?
Ex: 1. e4, e5?

I mean, I get it that Q= queen, N=knight, B=bishop etc... and I understand the coordinates, but what's up with the above example?

 Thanks.

Some more notation conventions:

x = capture

0-0 = castling kingside

0-0-0 = castling queenside

+ = check

# = checkmate

e.p. = an en passant pawn capture

If you notice there are letters and numbers on the side of a chess board. a-h correspond to colums, for white, a is the rook's column, b is the knight's column and so on from left to right with h being the right rook's column. The numbers 1-8 correspond rows, from top to bottom from white. Now, b=bishop, N=knight, r=rook, q=queen, k=king, and no letter like e4 = a pawn move. The first letter tells what peice is moved, the next 2 tell you where it is moved on the grid. x=capture, 0-0 = king side castle, 0-0-0 = queen side capture, (I forget check), #= checkmate. Now to rate moves people use Question marks and exclamation points in the notation. != a good move, ?= not a good move, !? = a surprising or possibly good move, !!= a phenomenal and often game winning move.
