No Start / Compression Problem

I have a 2002 Mazda Tribute LX, 3L Engine, with DOHC's. It stopped running awhile back and hasn't run since then. I did a spark test on it and found that all six cylinders were getting a spark. I tested the fuel system and the fuel pump was pumping fuel. After doing a compression test on all six cylinders I discovered this:
Cylinders 1 & 2 had 30 psi.
Cylinder 3 had 37 psi
Cylinders 4 & 5 had 0 psi and
Cylinder 6 had 150 psi which is which I've been told is in the range the compression for all six cylinders should be.

My questions are:
Does the 0 psi of cylinders 4 & 5 indicate a blown head gasket between those two cylinders and possible broken or badly damaged valves?

Also, are the low compression readings in cylinders 1, 2 and 3 indicative of valve damage and a blown head gasket also?

I am a automotive tech student with limited diagnostic experience and I could really use some expert input. I really need to repair my vehicle and get back on the road. Any help that anyone qualified to comment on my dilemna will be well appreciated.
