buy a compression testing tool from wal-mart/advanced/autozone for $20.00. run the test. it's really easy and effective. if you need help or have questions pm me.

Dying to pull the motor out eh? Why go straight for the pistons and rings? Just want an excuse to rebuild? 
Pull a V/C, the one rocker arm bolt and take a look.

just borrow theirs!!
Well i'm kinda in a budget. I dont want to spray. it's just not long term and don't have the $$ for long term prob's.
I pulled both valve covers off and everything looked good/normal nothing out of the ordinary. HOWEVER my plug was FUCKED.

before you go and buy new pistons and rings i think you need to find out whats wrong with it, if i had to put money on it i would bet you have a broken valve spring or a burned valve, probably broken valve spring, with only 30lbs. compression thats not going to be the piston or rings unless you have a big hole in the piston. good luck.

thanks a lot really. well i took of the valve covers and i didnt see any noticeable damage to the springs. Do you think it's a good idea to take the heads off before i do anything else? is there anything in particular i should look for? How do I do a leak down test? Can anybody please tell me how this works exactly? what do i need?

The easy way (now that your V/C's are off) is to remove your intake and exhaust valve rocker arm bolts (10mm). Then use a leak tester. Pull out your pushrods and look at them in your hand, I've still got my money on them looking like the Mcdonald arches!
