I'm nowhere near as good as others who play this. I'm trying to fight Skeletron, and he stomps me hard. Granted, I've only got 120HP (only found one heart container so far), but with this ice sword I got that shoots iceballs out every 1 second of swinging for 10+ damage each, I've been able to make it to the Shadow Orbs (hearts) in the Crimson. I just don't have a nightmare pickaxe to bust through to get to them. Skeletron is the only boss I have access to (does he even drop the proper hellstone for the pickaxe?)

Keep in mind I have platinum pickaxe, a dope-ass 16 damage magic ice boomerang, tunsten helm and armor, and platinum greaves. Also, I dig the pink dyed raincoat.
