I have some Alex rims and formula hubs on my FG commuter. My commute adds up to 5-6000 miles a year and I've been on this setup for two years. The hubs have not been an issue and it rains here 9 months a year. They still spin well.
As far as the rims, the best thing you can do is get a quality build. You *can* learn to build them yourself. A quality build will hold the rim true better than anything else. When I got my wheels, I re-tensioned all the spokes myself. The wheel holds true today. A good rim on poor or uneven tension will suck.
