Ok, go on then. If you used Ohms law, the values you have calculated are the required values of resistance in ohms. Without checking, they look about right. Check the store to find resistors of the nearest value (rounded up).
Alright, thank you so much, that helps out a lot!
I got 1 ohm, 2w for the red.... Hmmm.... That should be okay, correct?
Just a quick follow-up: my calculations were based on driving each Led at 1000mA.
Ohms: (3.7 - 2.59 )/1 = 1.11
Watts: (3.7 - 2.59) * 1 = 1.11
I personally wouldn't round down the resistor to 1 ohm. There's a 1.2 ohm available in the store.
We all have to start somewhere. The journey is all the more impressive by our humble beginnings.

Tim probably found a better deal on the 3w resistors when he was buying them in bulk for the store. When shopping for electronic components, some sizes are just less common (and therefore more expensive).
Don't worry, the 3w will work just as well as a 2w, and they won't be bulky like the 5w and 10w resistors.
