There's no such thing as a noob- Wait, hmm, there are. Well, lets just say that the way you asked the question shows a desire to learn in a way that was definitely not noob. If you don't ask questions, you never learn, but the way you asked the question will probably generate you a better answer.

The answer is "well, sort of". Blacksmiths and Engineers tend to be almost entirely focused on themselves, since most of the really good gear and items are Bind on Pickup. The idea behind this is to not only create a "special" feeling behind the items, but also allows them to increase the item level (ilvl), which increases the amount of stats that can be applied to the item in question (item budget). They both have some toys in Burning Crusade that can be handed out to others, but Blacksmithing has more Bind on Equip items to hand out, like the felsteel tank stuff. They can also sell sharpening stones that can be fairly helpful if you don't have a shaman in the party giving you a weapon totem (for example, Windfury before the 3.0.2 patch) and shield wards that can be pretty nice for tanking.

Note that this stance has largely been backed away from in Wrath of the Lich King: a lot of new and cool items are available from Blacksmiths that are Bind on Equip for a lot of classes - there's even a caster dagger, if I remember correctly - that would have been unthinkable in Burning Crusade. Engineers are also going to be making motorcycles, finally giving them something to sell (besides arrow and bullet makers and the tank gun) to sell to other players.
