Tie Rod Replacement

[Bhatti, Mohammed]

Ok folks,
 
Looks  like it's time for me to replace the tie rods on my 97 A4 18tqa.  I've just been quoted $800 from a local mechanic after I dropped it off for a alignment check.  Went ahead and ordered both tie rods for $90 from germanautoparts.com.
 
Anyway, is this something that can be done over a weekend if I work slowly and steadily?  What tools would I need?  Am I in for a long, hot, tiring weekend with an achy back at the end of it?
 
Any info, helpful hints and experiences greatly appreciated.
