Answer 1

Just to follow on from Mark... most of the tables in the Magento database are InnoDB. Whilst the query cache can be used in a few specific places, the following are more directly relevant...

innodb_buffer_pool_size
innodb_thread_concurrency
innodb_flush_method
innodb_flush_log_at_trx_commit

I also use

innodb_file_per_table

as this can be beneficial in reorganising specific tables.

If you give the database enough resource, (within reason) the amount of traffic really doesn't load the server up at all as the majority of queries are repeats anyway, and are delivered out of database cache.

In other words, you're probably worrying about nothing...
