Control Arm and Tesnsion Strut Work

[cwildman]

Long time lurker. My '04 E53 3.0 just hit 200K miles and I'm trying to determine how much money I should keep putting into it.

About half a year ago I took the car to an independent BMW shop in Portland for some basic work. First road trip the night I got my car back the transmission cooler blew off and somehow there was a huge chunk missing off one of the pulleys. Fast forward to this week, I decided to take my car into a dealer for the security that they won't screw up.

Took the car in to try to see if something is wrong with the power steering (seems pretty stiff at slow speeds), they didn't find anything. However they want to do the following:

Replace Tension Strut Bushings (Found Tension Strut Bushing Worn) - $508.26
Replace left front outer CV joint boot (Found CV joint boot(s) torn/leaking) - $639.50
Replace right front outer CV joint boot (Found CV joint boot(s) torn/leaking) - $639.50
Replace left rear upper control arm (Found control arm bushing(s) excessively worn/loose) - $1,236.91
Replace right rear upper control arm (Found control arm bushing(s) excessively worn/loose) - $0

I've had mechanics complaining about the CV boots being torn since forever but haven't really had it matter. Is it going to be a serious problem one day? If I want to keep driving this car should I have these tensions struts and control arms replaced? Assuming the wear and tear of an X5 with 200K miles, any safety risks?
