What does this mean?
 

I just got my car back from the shop, where I finally had my ABS system repaired. On the notes section on the receipt, the mechanic lists some problems with the car.....but when I called him to see what they mean, he is on vacation! So I was wondering if you guys can
A)decipher what he's referring to (as in, what part of what assembly am I looking at?)
and
B)can I fix this stuff myself?
Here's what is says:
"Needs power steering update" (does this mean a new rack?)
"Oil leaks @ rear cam carrier end cap"
"Possible leak @ cam carrier gasket" (Is the "cam carrier" the housing around my camshaft?)
"front cam o-ring leaking" (is the front O-ring the seal for the gear/shaft behind the distributor? I just changed my belts this past weekend and everything was bone dry, no visible leaks).

Anyway, some guidance on what this means and whether any of it might be serious would be very helpful. Thanks!

Power steering update is replacing the old hose from the reservoir to pump with a different design.

Sounds like the cam box and seals are leaking, if you can do the timing belt, you can replace all the gaskets and seals. The front o-ring is between the cam box and front cam bearing housing (the bit the distributor cap bolts to)

Britwrench, you are a veritable fountain of knowledge. Thanks!
Know where I can find instructions on fixing this stuff? Is it covered in Haynes?

Don't forget to ask for the new banjo fastener when you get that hose - they're now a two-piece unit.
