It's up to you whether you'd want to go with cooler plugs right away or just regap the stockers.. BMS has made comments about map1 likely being "safe" with regapped stock plugs.
I'll add my own data point. Daily driven for a couple thousand miles now, I've found that the stock plugs regapped to be working well so far. That's with 93 octane and a custom map 6, pretty similar to map2. I don't baby the car, but I don't abuse it either. It's also the cool season, but I'll see how the stockers hold up to 90+ degree heat in a few months here in the South. However, if I were gonna beat the piss out of the car and/or track it I'd probably upgrade plugs right away though.
