Yes, you do need o2 extensions. You will need two, but I have heard of some people getting away with 1.... But Id get the two just to be safe (its what I do). Not sure on the length, but they dont need to be killer long.
Order yourself some Felpro gaskets or Stock replacements, they work great.
EDIT : Good choice on the stage 8 locking bolts too, you wont regret it.

Hey, I think you are going to need 2 extension's no matter if you are obd1 or obd2. A good way to check is to pop the hood and see if you have one on both banks. Obd2 cars have 4 o2 sensors total and are going to have dual cat's w/ an o2 sensor behind each cat. obd1 is just going to have have 2 o2 sensors and 1 cat, w/ nothing after the cat.

Yeah, even if you have one cat you still have 2 O2 sensors. One in each manifold no matter what.
In OBDI cars there is 2, just two pre-cat O2 sensors to tell the PCM how the engine is running, and what changes are needed if any to the A/F ratio.
In OBDII cars there is 4, 2 pre-cat and 2 post-cat (the 2 pre-cat O2s actually take readings on the A/F and tell the engine how to run like stated before, the post-cat O2s only check to see if the cat is working).

If you want to confirm what connector you have (I forgot what years have what) you can just look under the car and see what it looks like (flat, or 4 pin square)...
I am almost positive yours is also a 4 pin though, just not 100% (real damn tired too).
