Don't worry about exposing to oxygen. As long as you don't go splashing it about or whipping it up there'll be no problem.
In my opinion secondaries are one of the best ways to improve a beer, second to leaving out large amount of sugar and followed by bottle conditioning.
Mr beers are fine for primary. For secondary you want to be under an airlock due to there not being as muchC02 production.
The other thing with a Mr beer kit is you have to prime in the bottle which can be a little inconsistent due to the small amounts to measure.
To tell you the truth the best thing about MR Beer id the simplicity and the education value. It's an easy no committal way into brewing.
