This guide gives a progression of items to craft. I don't know if the guide provides the most efficient route to 300, but it might be worth a look.

The second link appears to be a thorough look at Blacksmithing in general. My hunter is at 300 Blacksmithing at the moment, but he took the long way. I usually made items whenever I had gathered enough matierals through normal play. I also found a few profitable items, and made more of these so I could sell them.

If you are still looking, there is a very extensive guide mirrored here:
