Hello dalli, Nepali passport renewal and US green card have no relationship at all. Just go ahead and renew your passport asap. You should not have let your passport expire. Expiration of green card doesn't mean your status as permanent resident has expired. The approved LPR status never expires (except the USCIS revokes it for some reason), only the physical card expires after 10 years. At that point you file I-90 for replacement card, right? Expiration of passport is more serious than expiration of physical green card. Every alien must possess a valid passport all the time.
