So long as you run Expedition #2 (for Buckets) and Expedition #37, you'll hardly run out of Ammo, even if you run a fleet with 4 BB constantly (as they'd need time to repair for saving Buckets). What you'd really need to stockpile for Events is Steel, as they're needed (in bundles) to repair big ships like Battleships and Carriers

And yes, clearing 4-1 and 4-2 should be easy compared to 4-3 which requires tremendous luck to get to the Boss Node (to balance being so easy to get to the pre-Boss Node), and I guess this is the reason the developers makes 4-3 map and ideal place to level some ships that can hit Subs (DD/CL/CLT/CVL)

For Carriers, yes, you should probably choose quantity over quality (as in getting several average level Standard Carrier rather than just 1 very high level Carrier) to counter Ship Locking Systems in Events. At least that's for CV, I leave the decision for CVL to you, cuz they are mainly used for branching rules instead of real firepower, sometimes for Escort Fleet in a Combined Fleet.

For now, judging by the number of buckets and resources alone, you should be able to pass Medium without any troubles (Branching luck aside, of course). I myself am still looking for Taigei, as I am afraid she might be needed for branching again =='... so yea, still hard for me to save resources. >.<
