Can I have 2 45 degree angles with a 8 inch piece of 2inch to my bathroom sink? The drain pipe is over to far to be in side my vanity. The the clean out and vent pipe will go strait up threw my roof from there.

You should be able to find a P-trap assembly available at any local hardware store.
The horizontal section should attach directly to the drain line coming out of the wall, while the vertical end should accept the tail piece from the sink.
Your system is almost certainly vented. Plumbing vents provide a path for sewer gases to escape so they don't bubble up through the P traps into your house under pressure (the sewer gases will expand and exert greater than atmospheric pressure), and the vents also keep water pressure from siphoning your traps dry, which would create an easy natural path for sewer gases to infiltrate your home.
So the comment about "wet venting" is right on target. As long as the combination of pipe diameter, the slope of the pipe and the distance between the trap and the vent ensure that the pipe doesn't run full of water (creating a siphon), a single downstream vent can be just fine.

If those are the only bends, and they are horizontal, and the total trap arm length is less than 5 feet, then yes. Trap arms can go thru no more than 90 degrees of bends without a clean out. Not including the vertical bends at the trap and at the drain/vent connection.
