SMB tip: focus on getting each family member(jackpot) on the upper playfield for the first 10-15seconds- there's a ball save on the lower playfield so you aren't risking anything.
Once those are collected, focus on hitting each family member(jackpot) on the lower playfield. Except for stewie- hitting stewie will only reactivate his playfield incase you missed a member on upper playfield.
After collecting all members on both playfields shoot for the evil monkey jackpot for a super jackpot.. Then repeat for increased jackpots and super jackpots...
Death tip: if you have him enabled, use him to your advantage.
With death raised and ball resting on left flipper- you should hit Lois99% of the time and with ball resting on right flipper with death raised should hit Chris99% of the time.
You'll start scoring better in no time.
