Answer 1

For a development environment, no I don't see any reason you couldn't shrink it (though you should never shrink databases in production, unless you're going to gain back 40%+ space and you need it -- shrinks fragment the indexes).

I would say for your dev environment, you probably want to disable most usage logging, unless you need it for a specific purpose.

Answer 2

You can shrink a SharePoint SQL Server database just like any other SQL Server database using SQL Server Management Studio. This is fine in a development environment, since you are likely the only person using it (might want to give a heads up to the team if there's more than one of you). Of course, there will be a performance impact on SharePoint itself depending on the size of the database - going from your screenshot above though, I don't think it's going to be big.
