Yeah, leveling one of the equipment crafts to 10 is pretty quick and easy. Also, don't worry if you actually level another craft as well, you can always take the points out later with a respec. For the most part respeccing is pretty cheap. In fact, its not a bad idea to have all you characters high level in both provisioning and alchemy for the passives they can provide. Getting to higher levels is easier with more points invested, but once there you can respec and just get the important passive skills, (Medicinal use for alchemy and the one that makes food/drink last longer for provisioning).
As for point distribution early on, I would tend to somewhat agree. Certain traits, like the one that helps research time are essential to have. Research is really the only long term aspect for the three equipment crafts. Also invest early in the hirelings. Other than that, you can level the craft solely on deconning materials. I'd even go as far as saying DON'T refine any mats until you can get all three points in the passive that gives better upgrade material chances. This is really one of the only ways you can get gold upgrade mats.
You can either buy in game or via GSCH marketplace the refined mats you need for writs, and for self gearing use dropped gear or if you want a crafted set have a guildy help you out and save spending the points until you have more available to you.
Of course, always feel free to ask in guild chat if you ever need help or advice!
