When saving SQL dumps through phpmyadmin or ssh, am I ok to use the default setting - which has 'create database/table' instructions and so should presumably be imported into a new database rather than an existing one (which'd produce 'already exists' errors).

Or is it better to faff-around with options like ''Add DROP DATABASE' and 'Add DROP TABLE', which presumably save a file designed for reimport into an existing database.

Knowing little about this, I'm thinking it's almost as easy (and perhaps more reliable) to create a new database into which to import the dumps - it's certainly easier and quicker when saving the dumps.
