You seem to be forgetting this point.
So, what do you mean when you say I don't need to know the status all the time? I planned on having the LCD screen(now leaning towards the matrix as mentioned by promacjoe) act according to the status of each and every reed switch on the board. Is this the wrong way to go about it?

Half of the 10x10 board.
I know, checkers only took up half the board
The most popular forms are English draughts, also called American checkers, played on an 8×8 checkerboard; Russian draughts, also played on an 8×8; and international draughts, played on a 10×10 board. There are many other variants played on an 8×8, and Canadian checkers is played on a 12×12 board.
Is it required that the LED matrix indicate the color of a piece on a given square?
Oh and will resistors be required for the reed switches?
Note their is no way to distinguish between the playing pieces if you use a reed switch, you have to infer what they are from software starting at a known point.
It depends on how you wire them. If you use an 8 by 8 matrix then you would need 8 resistors.
