Clutch not Disengaging?
So when i was done rolling the quarter panels, i tried pushing my car out of my garage because i didn't want my garage to smell like gas but something was stopping it from rolling so i jacked up the rear end up and spun one wheel and the other wheel was going in the opposite direction which was weird because i just put in a s4 na lsd in it. So i turn on the car and try to get both of the wheels spinning and as the clutch started grabbing the rpm started to drop like something was holding it from spinning and than it eventually died. Turned it on again and revved even higher and once the clutch gripped something sounded like something snapped, but both of the wheels began to spin the same direction. As i drove off i noticed i couldn't pull out of 1st gear even when the clutch was fully pressed. I'm really not sure whats going on and was wondering if i could have some guidance of what it could be. When the car is off i can shift to some gears smooth but when i turn it off i cant switch to any. I already bled the master cylinder
Sorry if its too much reading. Thanks in advance!

As for your real issue... What does the clutch pedal feel like? So, did you rev the engine REALLY high, drop the clutch, and then that is when you heard something snap??

I've had some cars that are just way too difficult to bleed the clutch hydraulics. My FC is one of them. Most come pretty easily, but my FC for whatever reason takes forever. The best way to bleed it is by reverse bleeding.

It can feel fine, trust me. I've bled the clutch on mine until I was blue in the face and it finally worked. It felt fine the whole time too. It's just that if you get a little bubble in there, you're completely screwed. I ended up tapping the slave cylinder with a small plastic mallet while bleeding to get every bit of air out.
You may be able to pop off the rubber grommet from the transmission bell housing to see if there are chunks sitting in there. You could very easily have a broken clutch.

Get yourself a buddy and put the car high up on jack stands (we support the rear wheels with semi truck drum brakes and the front a arm with 6ton snap on jacks for good measure) and pull the trans with out arms. It isn't heavy by any means. Just be VERY cautious if the input shaft and pilot bearing on the way out. We can have the trans out in an hour or two depending on how much bullshitting we do.

You cannot damage the clutch by rolling fenders, even if the car's in gear. There's more stress on the drivetrain while cruising than you could put on it by rolling the fenders.
Given your scenario, my bet is still on faulty hydraulics.

Pulled out the tranny and the clutch seems fine but the pilot bearing was seized up. Maybe abou 2000-2500 miles on it. I dont recall lubing it or putting a pilot seal on it. Could this be the reason why it seized up and why the clutch isnt releasing all the way?

Usually the pilot bearing is a small needle bearing or a brass bushing. If it's the needle bearing type, you can see the individual rollers. Otherwise, you have a brass bushing, and it's not seized.
Check the fork, see if it's bent, look for any signs of damage around the pivot point, look for signs of excessive wear around the fingers of the pressure plate, check and make sure the pressure plate is still properly torqued down.

When we took off all the bolts and was ready to pull the tranny off, it seemed stuck and found that the pilot bearing came off with the tranny when it suppose to stay on the eccentric shaft. Also you cant see any of the needles anymore. So what i was thinking when the tranny was on the car is that having the pilot bearing seized up, it basicly bypassed the clutch and was always spinning from eccentric shaft straight to the tranny.
Heres some pictures of the clutch fork aswell

Oh wow. That is definitely an issue. Get a small 2 or 3 jaw puller and get that thing off! You also need to inspect the eccentric shaft and transmission input shaft for damage. And yes, you should have definitely put in a little grease once the bearing was installed, and seals always help too 
I'd go to your friendly neighborhood Mazda dealer for that, as most clutch kits will not supply the seal.
If they don't have it, Mazdatrix is only a couple hours away from you, and they both pieces for about $12 total.

I just hope the eccentric shaft isn't scored or heat-spotted

as a haeads up, when you spin 1 tire forward on an LSD the other tire should also spin forward. but i believe when you spin 1 backward the opposite spins forward. dont quote me on the second part but i know the first is true
