Hey 82SC,  the a-arm bushings look like a good two-to-three-day project and I don't think its the best choice in replacing bushings.  I'm planning to do the turbo tie rod replacement and the rear swing plate bushings and banana arm bushings on the same weekend.  These should cost about a hundred.  And from what I have heard, these bushings are ALWAYS in need of replacement if they are the OEM.  Moreover, I believe that the tie rod and swing plate bushing replacement require an alignment so you might as well do them at the same time.  I don't believe replacement of the a-arm bushing requires an alignment. So in the interest of saving some $$$ I would suggest the rear bushings replacement.  Of course after the tie rods and after you sell the tie rod tools . . . . to me.   
Let me know how it goes.
