Parts/Labor cost. Acceptable?

[Dza]

Auto Gallery (local Subaru guys) have come up with the following fix-it costs to some of my major problems:

Valve Lash Adjuster: part - $50, labor - $490
Right front axle: part $170, labor - $98
Rad: part $800, labor $98
Steering rack is leaking: part $1996, labor $295

Well, I'll be doing the valve lash adjuster to finally get rid of the ticking, and the axle (previously diagnosed by 3 other shops as catastrophic exngine-pull-necessary multi-thousand repair). But I can't do the others, as they are too pricey and there are options compared to new OEM. He is looking into the knock sensors for me, and I'll have those done too to get rid of the CEL if necessary.

Are these prices fairly standard? Keep in mind these are in Canadian dollars. $1USD=~$1.12CAN. Also, this does not include tax.
