In leveling up the blacksmith, he will definitely craft some gear that is of no use to the monk (for example, a two-handed sword). Does he eventually craft gear that is monk-specific? Is it worth leveling the blacksmith to the point where such gear becomes available?

Yes, he does craft monk-specific gear
You can start crafting a Daibo at Level 2 (2H Monk weapon), and Monk fist weapons at 60% of Level 3
Currently, the blacksmith is just a big money sink where you can spend materials and money for a chance at some great items, but it is often better to take that money and buy a good item from the AH.
Still, it's nice for keeping your armor up-to-date while you level, and saves you the time and hassle of searching the AH for items :)
Looking at the Blacksmith's progression, it seems at the end of Level 3 he gains the ability to create an Adept Shuko. So, yes, the blacksmith can eventually craft Monk-specific gear.
Currently, though, it's not worth the effort to level him up; the auction house provides items at a much better price-point.
I would disagree, once you level the blacksmith up he can be used for all your characters. This alone makes it very advantageous to train the blacksmith to level 3 or 4
