That's a better idea.
You really need an income of supplies. If you have only one character, you may want to do a gather/crafter, like Mining/BS, Mining/Engy, Tailoring/Chant, Herb/Alch, etc, like you've chosen.
If you intend to have more than one character, many perfer the pure gather approach, mentioned above. You get as many resources as you can for sale, and you can pump them to an alt that would craft as well. While you'd need to get the alt up to a level where it's high enough to get the desired cap (35, at most), you want your main character to be exclusively a gatherer. This way, the one you play the most can use the time on it, and the higher level areas on it, to gather. Plus it's more money to see the extra supplies or/and crafts!
