Although what has been said is true, given that you've barely scratched the surface of Weaponsmithing, if you do feel like making a switch, now would be the time.
My first char (burg) is weaponsmith, and passed off the gems to my second (jeweler). Great combo.
My third (guard) is an armoursmith.
You make a weapon once every ten levels, not much else. You can get weapons from the AH, from drops, and when you get a symbol, not a big deal for someone else to make a Second Age or First Age for you--particularly if you are a prospector providing mats.
You can make armour up until Moria stage, then drops and instance armour tends to be better. Crafted shields tend to be useful throughout, if not to you, to your mini friends.
Same with jewelry though, crafted is always under instance drop par, so you CAN make some when level cap is raised, but then replace it when you get instance drops.
Consumables however, you'll always need. Food, scrolls, pots...
So in your case, switching to armoursmith will have benefit.
In others who read this thread, past Moria it's handy to be able to farm/cook, or scholar, and food always sells on AH for a pretty penny.
