definitely consider using alter table exchange to lessen impact.

if you're not familiar with it, it lets you swap data between a partition and a non-partitioned table. so you load the data into a "temp non-paritioned table", build the needed indexes and then do the exchange, and poof its there(ok pretty darn close to poof).
