The installation on your car is pretty straight forward since you have full exhaust system. Keep it above the horizontal and at least 18" from the tail pipe. Open headers have their own challenges.

It really helps to quickly get the mixture close. But don't bet on any specific number for the best ET. Combine the detailed info of the wide band (vs time and rpm) with the time slip for fine tuning. But it really does give solid data to make decisions by and see effects of changes.

For a street car it really gives lots of info for idle, part throttle, etc. Worth every penny if you want to fine tune things, IMO. And for street driving at part throttle, a display in the car would be helpful, the screen on the LM-1 is a little hard to read while driving.
