Sounds like you got it figured out, mostly.

Yes, the bolt tightens the bracket on the sensor.

As long as you make sure the vanes on the back side of the balancer aren't going to hit the sensor as it spins, you're good to go. That'* what a feeler gauge can be used for, ensuring that there'* an air gap there.

Worst case scenario, you tear your brand new crank sensor to shreds when you crank the engine for the first time. Well, and possibly damage the balancer vanes too...

With things not-touching though, you'll be fine. Just double check it before you crank it over.

Looks good.
You'll want to leave the center bolt loose, while you adjust it, installing the balancer blade vanes between the sensor slots. Then set the gap with the feeler gage and tighten it down.
Instructions should also come with the new sensor.

Any idea how long it'* been since it'* run?

Your IAC valve might be sticky/dead. It'* located in the throttle body, and controls the flow of air into the engine at idle. If it'* stuck closed, you have to keep your foot on the gas manually to keep it from stalling. A search of "IAC" and "clean" will tell you all about that.

Could also possibly be a bad MAF sensor. That'* also on the TB, the rather large plastic rectangle with three screws and an electrical plug. I've never done it, but I'm told that if you unplug the MAF while running, it will run better if the MAF is bad. Or maybe you unplug it, then start it...? Hopefully someone who has done it will respond with the correct procedure for that.

I'm sure there'* other possibilities, but those are the first two that come to mind.

If it runs, you got the crank sensor right, anyway. Make sure it'* tight, and move on.

Keep at it, you'll get it going.

Did you clean the IAC or unplug the MAF? Results?

Check for spark at each of the three front cylinders.
Check for fuel at the rail.
Edit - You should also check for trouble codes. The following link explains how.
http://www.bonnevilleclub.com/forum/...e=article&k=57

Where are you located? There may be a member near you that can lend a hand.
Have you checked the condition of the spark plugs?
Is this a car you just bought that wouldn't start?
