Default O2 Sensor Issues

I have a couple of questions for you gurus out there. I may need to replace my O2 sensor. The car has been getting horrible milage, like 10 mpg. Everything is fine on the car, aka, no leaks etc. I'm going install my LC-1 to confirm if it's running rich. Here's my questions:
  1. What are my O2 replacement options? I've heard that universal ones aren't the way to go but the factory replacement is $150!!!! Are the bosch universals any good? Any recomendations?\
  2. My O2 sensor is stripped. I can't get it out of the manifold with the O2 sensor socket I have. I did soak it with penetrating oil before trying to remove it. It just wouldn't budge and it stripped. Do I have to remove the entire manifold, up pipe, etc to get the sensor out? I'm trying to avoid that if at all possible but I don't think there's enough room for a pipe wrench in there. For that matter, I'm not sure it's even possible to remove the manifold with the O2 senor in there. Any advice?

One more question:

Can my LC-1 Function as the factory sensor? This is a precat sensor.

I figure if I have to install my LC-1, maybe i can use it for the ECU too.

Ok here are my options so far:

Factory Denso Oxygen Sensor, Front: Part Number 234-9011, $150
Bosch Oxygen Sensor, Front: Part Number 15537, $260
NGK Oxygen Sensor, Front: Part Number 24659, Cost?

I think it looks like the factory sensor will have to do.

If you do Bosch check the lenght of the wire before you buy. The O2 they make for my car is about 6 inches too short. Personally I just prefer factory since it's less of a hassle.

What about using the simulated narrow band option on the LC-1?

You can also use these parts:
Airtex P/N 5S4302
Walker P/N 250-54004
ACDelco P/N 213-2843
Subaru P/N 22641AA042

Regardless of the brand, you'll find a Denso AFR sensor in the box.
