Removing Timing cover from 4.4

[nicksrover]

I just purchased this 2006 LR3 4.4 SE from an auction. Overall nice car , and going to give it a shot in fixing. Left bank(when looking back at the front of the motor) all has good compressions in the 150's-160's. All on the right bank are 0-15psi. I have discovered that this is a non-interference motor, so now I have decided to try and fix it. After pulling the valve cover, the chains appear to be intact. I am wondering if the tensioner has come apart or it somehow skipped a tooth. A few questions

Is there a thread out there on replacing timing components?

How in the world do I get the accessories off of the motor (lower right power steering pump and A/C Compressor)

Any info out there I could be pointed to would be greatly appreciated!!

Thanks
