 Rebuild Indexes
I did an user export, and included indexes, constraints etc. so I can import into a snapshot database (for historical purposes). I was wondering if it was necessary for me to rebuild my indexes if they were included in the export?

I do not think it's required. If you face performance problem after importing, then you may consider this option.

exp/imp procedure -when including indexes- takes care of building indexes on target database and moving source database statistics to target database objects.
Actually, since indexes are build from scratch during exp/imp process you are doing maintenance -reorg- them.
