I have a Tempered Calibur. I want to ty to be the helpful bomber. So I need to think, what bombs should I have a blast bomb and Spine cone. I want a AOE and a few more when I get wep slots. I have a Drake Mail and planning to get Angelic and go to Fallen helm.
WHAT LOADOUT SHOULD I GET TO FIT ALL AREAS OF BOMBING(CROWD CONTROL,STATUS AOE AND DAMAGE)!!!
Check out the Bombing Guide in the wiki. It'll help quite a bit with planning your bomb arsenal.

In general though, grab these for...
Crowd Control - Shivermist
Damage - Nitro or DBB
Status - Ash, Voltaic Tempest or Venom Veiler
It is great that you have a Calibur already, it is a good sword for a bomber. That way you can use a Levi + three bombs. As a bonus, it pairs perfectly with the Shivermist by allowing the charge attack to connect three times.
A bomber benefits from having CTR Max on the bombs, so consider switching to bomber armors or Bomb Focus trinkets. The guide goes into this in detail.
