You can find some sample numbers here:

Not SQLite.  Either MySQL or Postgresql can scale to very large databases, so 
I'd pick whichever one your site has more expertise with.

Probably not, as I suspect that either OS resources (network and volume IO, 
mostly) and the database performance will be your primary bottlenecks.
