1: Your setup with main gun always failed to api 5 as B.B.R. If you want to do Maya cut-in setup. Use the H.C.R one/ High angle gun, 25MM radar and 90 mm one. That yield the best api of ten. 10cmHA x2 / T91AAFD (API 9) is H.A (R) so it has an api of 9 value. However, keeps in mind that individual AA status of each kanmusu is also important.

2:To farm hoppo and killing world 3-5 at the same time. From lv 120 hq experience. It requires you to have good upgrade guns, reppu and high level ships (married is better).

The good and best works so far with less res burned. 3CA/CAV 3CV < All of them suppose to be at lv 99+ with good equipment upgrade. You can enter yasen at hoppo node if necessary (most likely you will) and still capability getting a S rank at boss node.

In your case, It's not enough to kill off hoppo because you have no sanshikdan (sanshikdan is super effecitve against hoppo which is install enemy). Having extremely hard time due to lacking of AS, your chance to trigget artillery spotting is decreasing.
