The resistors you received are identified by the colored bands around them. There a bazillion websites that do color code deciphering. If that doesn't work, invest $3 in a Harbor Fright DVM. For a dollar more you can go high class with the backlit model. Use the ohms ranges to measure your resistors.
Just throwin' this out here-Using the 12v PS output, and assuming a Vf of 2 volts, 5 LED's in series would make the total voltage 10 volts. Once again, assuming an If of 20ma, you will need a resistor to limit the current from the 12v source to the 10v diodes. R = E/I = (12 - 10)/20ma = 2/.02 = 100 ohms. P = EI = 2 * 0.02 = 0.04 watts. A 100 ohm 1/4 watt resistor will work well. For 100 LED's, there will be 20 rows of 5 LED's. Each row will have its own 100 ohm resistor and consume 20ma. 20 rows at 20ma each will be 20 * .02 = 400ma total. You can do this with a 12v, 500ma(or more) wallwart.
If your Vf and If are different, rearrange the # of LED's in a row and the # of rows to get a total voltage of a couple of volts less than the supply and figure your current limiting resistance accordingly. LED's are pretty tollerant. 20ma is a real good number to run them at. The Vf can be found on any LED website. Every different color LED is made from a unique material with its own Vf.
