In terms of the mission ahead, there are two realistic bases of operation;
>A) Diego Garcia, about 14-15 Hour Mission time, likely only 1-2 refueling required
>B) Guam, about 35 Hour Mission time, likely requiring 4-6 refuelings

USAF official fact sheet states the B-2 has a payload capacity of 40,000lbs, and the GBU-57 MOP is a 30,000lb bomb, so if they're carrying 2 there would need to be considerations regarding fuel at takeoff, also aerial refuelling requirements are more severe

Two MOPs would require taking off with less than a full fuel load, as evidenced by the HIFIs going for immediate tanking after take-off. A payload 150% of MTOW would hit range significantly, which I think make Diego Garcia more likely a base than Guam.
