When visiting Wrecked Ship without Speed Booster, you'll want to use the upper door to check the Reserve Tank location, using either Wave Beam or a Power Bomb to break the item's shell. This way you know whether you will need to return for that item later after you obtain Speed Booster (or to help determine if Speed Booster is even required for that seed).
The optimal strategy, the "Robot Flush", fires two shots downward to push the robots into the pits from the spiked area.
After charging the shinespark, walljumping up the shaft can help conserve energy for the Gauntlet Spark.
