Minor typos:
p.34, exercise 2.23: Second sentence should start "For each finite subject $J$ of $\Lambda$".
p.48, exercise 3.27(i): The bracketed text should read "Use Exercises 25 and 26".
p.71, exercise 5.23: The hint should start "The only hard part is (iii) => (i). Suppose (i) is false".
p.88, exercise 7.27(v): The last clause should read "the homomorphism $f_{!}$ is a $K_1(A)$-module homomorphism".
p.127, index entry for "flat, faithfully": Should cite p. 46, not p. 29.
