CHECKPOINT prevents database drop
No, Logs cannot be disabled.  Even if you set the database option for SIMPLE recovery model, the log will still exist since it is necessary for transactionally consistent activities, which are a mainstay of SQL Server.

Nonetheless, running in the SIMPLE recovery model should reduce the conflicts that you are facing.  Since this is SQL Server 2008, why not try getting rid of the database prior to rebuilding with something like the following:

EDIT: Minor update to script to show how to keep control of the database. 

USE master;
GO
ALTER DATABASE yourdatabase SET RESTRICTED_USER WITH ROLLBACK IMMEDIATE;
GO
USE yourdatabase; -- So that you become the SINGLE_USER for the next step
GO
ALTER DATABASE yourdatabase SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
GO
USE master;
GO
DROP DATABASE yourdatabase; 
GO


The first ALTER may not be necessary, but it helps prevent someone else getting in as the "single" user.
