What changes has to be made on the curcuit to make it possible to use with 12V instead of 5 V?

You are talking about voltage, not current. And yes, you should be able to use the circuit with 12 volts just by recalculating proper values for R1 and R2. I haven't tried to run this from 12v myself but give it a try and tell us how it went. :)

Well, since I was thinking of using it with a LaserLed (like the ones sold at ww.only4pro.com) couldn't I just remove R1 and R2?

If you are not going to use that power led in the first place, just remove the R1 and the led connected to it. Laserled unit have the needed resistor so it should work ok. Can't give you 100% quarantees but ... :)
