200 - 400 tables is too many.
Is it too many for merge, innodb or both?
Try having one CUSTOMERS table. You know who is logged in, so you can use that information in a WHERE clause.
Yes, but If somebody would find a password (maybe using brute-force attack) to one account, could delete data of other users...
