You might have clearance issues with the brake calipers and rubbing on the suspension with that offset.I've noticed these cars like something north of 30 for offset.Mine are 35+ offset, no spacers and no rubbing.Play around with this calculator and you'll get a better idea of what fits

Yeah, definitely won't start with a bad crank sensor.You can try bleeding the clutch, sounds like it needs some fluid and a bleeding. Any leaks on the slave or the master cylinder?
*Update*So it's raining down here, couldn't work on the car like I wanted. I did however turn it in for a few and noticed injector number 4 leaking from the rail. I have o-rings, no big deal. That will have to wait until tomorrow.
