E34 Front suspension question

[Seung Hyun Chung <schung@xxxxxxxxxxxxxx>]

I'm sorry for repeating this message. I had trouble getting the digest 
for awhile. Anyway...

After having my front struts replaced in my 89 535i, my local mechanic 
wrote on the ticket, "Idler arm has slight movement, also both sides 
brake reaction rod has movement and boots have been torn for awhile and 
grease is full of dirt."

Does anyone have an idea as to what these terms mean in BMW language? 
Control arm maybe? Please help me understand what he is talking about. 
Given you understand what the mechanic is talking about, is it hard to 
replace these parts without special tools? How expensive are the parts? I 
already have the Bently manual for the E34 so if I could only figure out 
what parts are needed maybe I could fix it myself and save mega $$$.

For those who have already responded to this message, if you can, please 
send the response again but directly.
