Well first off, Necro increases your running speed over a certain amount of time while running (like a few seconds for max speed), not instantly, and it doesn't increase your jumping distance/height. Just use Shadowmail while fighting the boss, and then switch to Necro while in the dungeon, that's what I used to do until I got Molten stuff. If you really want melee speed while killing Skeletron, use the Muramasa with full Shadowmail, 3-4 feral claws, and a band of regeneration and/or shiny red balloon (if you want an easier way to jump around while fighting, otherwise use the band of regeneration).
Personally as of now I just annihilate anything/everything with Molten armor and the Molten Greatsword (or whatever). With a few feral claws on, that thing is literally as fast as the Muramasa, and it's very nice. I'll only use the Sunfury, (used to be my favorite weapon), for killing hordes of monsters like a goblin invasion if I am not using the Star Cannon or if I'm out of ammo.
