Now I have a few questions.

How Important are the lines?
Important
If I block off the mettering unit and pour oil into the gas tank, will everything be okay?
Yes, though you will need remove/cap off the old lines.
At what rate is the oil released into the motor? How much PSI is the oil being sent though the lines?
Dependant on throttle position. Use about 1oz. 2cycle oil to 1 gal of gas. Almost zero PSI, and very little flow. Think of it as more of a dripper than a pump.
Are there other material I can use besides the plastic lines?
If you rebuild the plastic lines with new tubing, they will last another 20 years. (or longer than the car will probably run) There are companies that sell the proper materials for $20-30
If I do replace all of the lines, I know I will have to remove the intake manifold. If I do this, are there any gaskets I will have to replace?
If you keep the manifolds/ throttle body as one piece, I think you will only have to replace one gasket (LIM to UIM gasket).

Thanks a lot for your time. Any and all help will be appreciated.

Mazdatrix.com for the gaskets

search for OMP lines to find the tutorial on how to rebuild them. (It may not be on this website.)

Good luck!
