Stockpiling buckets won't be that hard as long as you keep running expedition 2, and a lot of the dailies also give you buckets as awards.

As for your bombers, tenzans are ok for the time being if you're doing all easy, but sooner or later you will need more powerful bombers like ryuusei or ryuusei kai. Do some daily crafting and maybe you can get a couple (for reference I use 50/60/30/130 and usually I get one 3 star planes out of 3 attempts, but feel free to consult the development page).
