Wiring my new garage and my electrician told me to use 2-2-4 from sub to main panel. I asked him about a ground rod or water pipe ground, he said only if i really want to? also when he wired the house he did'nt ground it, he said it is better to have it go back to the source, the pole? Am I going to die?

Probably won't die but he is an idiot. For your main panel you need two ground rods eight feet apart with a single ground cable connected to both plus the panel. A bond on both sides of the water meter connected back to your panel is also needed with the same size cable. Ground wire size is dependent on panel rating.

Oops forgot about the garage. Put a ground rod out there for the garage panel and make sure all circuits are GFI protected. BTW you should have a real electrician take a look at what this guy did just to be safe.

What size circuit breaker? I am assuming that it's aluminum which is 90A max for your application. Is the garage attached or detached & are you in a no inspection area?
I have a 100amp sub but i'm only going to have a 60 amp in the main. don't need that much power. In the main panel he has grounds and neutrals on the same bus, but the bonding screw is in place. So at the sub I need to install a bus for the grounds only to go on to the ground rod?

Like the other poster said, your electrician doesn't have a clue.
If you have to question his installation methods, it's obvious the person you're hiring isn't qualified.

Direct burial rated 2-2-2-4 or 2-2-2-2 is perfectly acceptable for direct burial. Its commonly called Mobile Home feeder, or quadplex.
You seriously need to find a new electrician, and don't take any info from this guy as the gospel. If he doesn't understand the code requirements and grounding any better than that, I wonder if he is even licensed.
In your main panel, if it has the main disconnect in it (and not before it such as at the meter) then you need to leave the ground and neutral bonded together at the main. If you have a disconnect outside at the meter, or somewhere before the panel, then the neutral and ground needs to be completely separated in your main panel.
