Try to only complete 2 of 3 lanes up top. That way when you're back down to single ball play it only takes one lane to relight locks.
Lock 2 balls on left orbit or right ramp, then shoot left orbit or upper right corner kicker for release. Re-lock 2 balls during MB for JP.
"Bonus Ball" is separate from "Extra ball" and is a timed ball played at the end of the game. Multi-ball is unavailable on a bonus ball.
Mini playfield lane completion re-lights lock after multiball.
USA lanes will increase the stop 'n' score multiplier. If you manage to raise it a bit, stop 'n' score can become pretty valuable.
A sweep shot of the upper 3 targets (usually from the left flipper, dropping all of them in one go) is 100K points.
Getting multiball at least once during your game will increase your bonus ball timer.
Both flippers will toggle the white/orange arrows on the right target. It's worth checking it's still on what you want after a slap save.
Spell "SHUTTLE" or "STATION" to re-light kickback and score corresponding award. Both flippers at once toggles right "change" target.
