Use painter's tape and tape up the front end unless you plan to install a 3M clear bra before the trip. Also, since the Manual only calls for the first 200-300 miles to be cruise free, and more so spirited driving to pack down those seals nice and tight, the OP has already met that requirement. Cruising on the highway with around 400 on the odom should be fine. The break in period is not extensive for this platform, as it's considered fully broken in at 1k which is pretty low in regards to other cars taking break in almost to the first oil change.
