I also had a look through the ODI guide and found references to much of the material I find most useful, including the two old faithfuls by Schiavo-Campo & Tommasi and Allen & Tommasi:
Managing Government Expenditure, Salvatore Schiavo-Campo and Daniel Tommasi, Asian Development Bank, 1999
Managing Public Expenditure, Richard Allen and Daniel Tommasi, OECD, 2001
It's worth noting that Tommasi has recently completed a guide in French for AFD (attached).
References to two articles by Tommasi and Allen on designing and sequencing PFM reforms are also useful. Both warn of the dangers of adopting formulaic approaches.
