Is there cause for concern that the payload is spinning along what looks like roughly it's normal axis. Can we assume that they equipped it with some sort of means for attitude control?

Spacecraft are commonly spin stabilized in order to keep them from tumbling. The same reason that rifles spin bullets or quarterbacks throw spirals, really.

And yes, it will have attitude control in order to ensure that the three burns (two complete, interplanetary insertion to come) all happen in the correct orientation

Yup. You could actually spot attitude control firing on the Starman feed at some point.

That's hilarious. Also note the 'Starman chilling out', he certainly is going to be pretty chilled.
