It sounds much like you're interested in the FRG's history. Although there are some trends unifying the histories of both zones, there is something of a bifurcation in the historiography.

For Adenauer biographies, Ronald Irving's Adenauer, part of Longman's "Profiles in Power" series, is a good start. Many of the other English biographies tend to a tad hagiographic. Alfred C. Mierzejewski's biography of Ludwig Erhard is another good biography on a crucial figure in this period, one of the more unlikely successors to Adenauer.

For the wider history of the FRG, the two-volume A History of West Germany by Dennis L. Bark is a good Sheenan-like text. Two anthologies are also of note: The Postwar Transformation of Germany: Democracy, Prosperity and Nationhood and The Miracle Years: A Cultural History of West Germany. These two anthologies cover a broad array of topics ranging from the postwar growth of exports to the reincorporation of POWs into German society. The Nazi period though is an inescapable reality for FRG historiography. Norbert Frei's Adenauer's Germany and the Nazi Past is a landmark text on Vergangenheitspolitik. Jeffrey Olick's In the House of the Hangman: The Agonies of German Defeat, 1943-1949 and The Sins of the Fathers: Germany, Memory, Method are good gateways into the processing of defeat and guilt. Rearmament was one of the crucial mechanisms smoothing over Vergangenheitspolitik and David Clay Large's Germans to the Front: West German Rearmament in the Adenauer Era is one of the better introductions to this topic. Ronald Graneri's The Ambivalent Alliance: Konrad Adenauer, the CDU/CSU, and the West, 1949-1966 is an excellent account of Adenauer's canny foreign policy which was more flexible than it might have appeared on the surface. Germany's Cold War: The Global Campaign to Isolate East Germany, 1949-1969 by William Glenn Gray expands on the Hallstein doctrine, one of the more lasting legacies of the Adenauer period. West Germans Against The West Anti-Americanism in Media and Public Opinion in the Federal Republic of Germany 1949–1968 by Christoph Hendrik Müller is like Graneri in that it examines how some FRG elite were less than enthused about their Ami allies and their often condescending attitudes towards the Germans.
