Bonjour Pauline
Congratulations on your new keyboard.
Everyone will have a different view, but without buying Tech Manager 7001, I found that the slowest way suited me best. After loading a few favourites to see me through my first gig, I then loaded one at a time and tweaked any settings before moving to the next one. Very slow, I know, but It's surprising how your song library soon builds up and you know they have been tested before playing to an audience.
Good luck with whatever method you choose
John
