[S] Worth of crafting?

[FV20X6]

I've got a Giant Druid (with oath) who got a drop of a chunk of iron fairly early from Brodda, so I finally gave in and raised magical infusion. I'm going with this skillset:

[Skills]

Throwing : 35
Wrestling : 40
Spellcasting : 40
Magical Power : 35
Nature Lore : 50
Magical Device : 30
Perception : 30
Dodging : 35
Spell Resistance : 40
Magical Infusion : 25


As usual for wrestling/throwing giants, it's been terribly effective; But on the same token I haven't seen lategame with a real crafter. What's my best option? Weapon to try to fill my quiver with custom javelins, since I don't think there's too much variety in throwable weaponry? Armor to simply cover up my resistances and get a high AC? Alchemy to go with throwing?

Speaking of alchemy: Is it ever worth it? I'm always glad to see potions of essences I find, but apart from flirtations with grenade flinging gnomish ninjas, I can't imagine it being a skill that you'd really appreciate towards the middle and end of the game, unless you can really make strong potions of poison and detonations.

I look forward to advice from the more experienced players, and hopefully I'm wrong about alchemy.
