I would go with neutrinos, there's an interesting article at http://news.bbc.co.uk/1/hi/sci/tech/4862112.stm
that's worth looking at.
By the way if it took less than a second for the suns light to get to us, as suggested above we would have severe sun burn, it's more like 8 light minutes.

Sunlight does have mass - sort off. This is because it is both a wave and a particle. This can be explained as dual-functionality.
Basically all that exists in the universe is energy. The terms 'wave', 'ray' and 'matter' are just explaning how the energy is behaving. Waves/Rays are traveling energy, matter is energy at rest. Therefore sunlight has mass.
As for the fastest moving thing with mass, who knows?
But may I sugest the Electron as it can move from one location to another instantaniously and is therefore infinitely fast!

The people that answered photon or neutrino don't know what they are talking about, since neither have mass. They haven't proven neutrinos don't have mass, but they will.
An electron is the fastest thing with mass. I say that because if you look at the standard model, it's the thing with the least mass greater than 0.

Galactic cosmic rays are probably the fastest. There are several types of particle mass in GCR's, which travel almost the speed of light:
"Galactic cosmic rays (GCRs) are the high-energy particles that flow into our solar system from far away in the Galaxy. GCRs are mostly pieces of atoms: protons, electrons, and atomic nuclei which have had all of the surrounding electrons stripped during their high-speed (almost the speed of light) passage through the Galaxy. " [See source 1.]
I think alpha particles (He++) are probably the second fastest of the particles with mass. See:
"What are the properties of an alpha particle?
An alpha particle is identical to a helium nucleus having two protons and two neutrons. It is a relatively heavy, high-energy particle, with a positive charge of +2 from its two protons. Alpha particles have a velocity in air of approximately one-twentieth the speed of light, depending upon the individual particle's energy.
" [See source 2.]

The fastest thing known is light, yet it takes over four years for light to reach our nearest ... there isn't enough mass in the universe to get you there It travels. 186000 ____ per second. ... Light has no weight and no mass.

As far I have heard, evidence suggest that neutrinos do have mass.
And photons have an equivalent mass in relativity according to Einstein, but I think you're discluding that.
So I'd go w/ neutrinos.

more mass = slower speed
so it must be the thing with the least amount of mass and the most amount of energy
I would say a photon

Lol.
Light has relative mass silly people. Meaning, it appears to us to have mass when we measure it because of its movement and energy it contains.
Photons have no real mass!
Jesus christ imagine being hit by light all the time...****, OUCH!!! AHH!!!!!!!!

I read somewhere that distant galaxies are receding at a good fraction of the speed of light

The answer is light. And yes, light does have mass. It can be proven.
