3.1 liter..radiator draincock/ fuel filter?

I tried to get the old radiator drain plug off, but broke it while doing so. I cant get it to unscrew out to drain, half of the wing peice to grip it is broken off, and im afraid that Ill make it worse. Once I do get it loose, does this drain-plug unscrew all the way out? Or is it permantly in there?


And how do I get this line off the fuel filter...the side going to the engine, or 'out' I can just simply use that line made wrench, but how do I disconnect this plastic hose connector going to the fuel-tank w/ out breaking it?.....


And also, does this motor have a overhead cam, or is just a standard? And does it have a timing belt, or a chain?

Thanks in advence :-)
