"and dont want to hassle with using Resister's."

Umm.. that "hassle" might prevent the LED's from exploding. Simple electronics tells us, not only does the volage matter but the amperage matters greatly. If you attach a LED straight up to power supply you run the risk of burning it out or blowing the LED up... do NOT do this... get a resistor into the mix.. 1/2 watt..

Ya,Ive heard about over-volting an LED and it pops...That would not be cool.So what resister do u recommend for a 3.5v normal (4.0v max) LED?

In other words to go from 5v(USB) to 3.5V...
