Here's the code for the resistors:
BB ROY from Great Britain had a Very Good Wife
Black Brown Red Orange Yellow Green Blue Violet Grey White
0 1 2 3 4 5 6 7 8 9

The first two stripes indicate the first two numbers and the next color is the multiplier. If there is a fourth one, it is usually a tolerance band (gold or silver) indicating 10% and 5% (can't remember which is which right off the top of my head).

So a 100k would be Brown, Black, Yellow, 330k would be Orange, Orange, Yellow
