Congrats on your M5 and lots of sleepless nights until delivery!
Check with your dealer or on the BMW website for M Driving School dates and locations.
Follow the recommended break-in as stated and keep traction control fully engaged until you have the skills and get to know the car...there's no room for error until you have room for error!
Keep your throttle settings modest until you get a feel for how the car accelerates, especially out of corners.
It's taken me about 6 months to figure the car out and I still have much to learn. I drove like a grandma for the first 2-3 months...even my wife was teasing me on the difference in my driving coming from an E92 M3.
Be safe and use good judgement and you'll enjoy your M5 to the max.
