Congrats on the new bike, technique will come with practice.
I do a rolling mount, and dismount, as I slow to a stop I stand and throw my right leg over then stop and stand. Of course I have been doing this for awhile, so even at 52 I can still manage it.
Have fun, ride the heck out of it. Practice some quick stops, so you can get used to the brakes, you do not want to get into a panic situation and grab the front brake hard, as the bike will stop, and you will keep moving forward. ;-)
