By binaries do you mean the shared components (mangement studio, etc),or the SQL Server executables (SQLMAINT.EXE, SQLSVER.EXE)?

Shared components, if you want them, need to be installed in each node of the cluster separately.

The SQL Server executbles are installed on system drive (normally C) by the install program when you choose a cluster setup but the master/msdb database are installed on the shared storage that can be failed over. For 2008, you will need to run setup on each node and choose cluster setup.
