May have missed the response to this, but my recommendation would be, yes. You need both the install and the update function to be implemented. The mysite_install would fire when someone who never used your module enabled it. Users who are upgrading will hit the mysite_update_1 function.

I have a stable release of the mysite module. In the new 4.7 release, I have added a new db table. Do I need to write a mysite_update() function to handle this? Thanks, Ken Rickard agentrickard.
