I used to be your size - significantly less now with regular riding. I was always breaking spokes. Then, I finally plunked down the cash for some strong custom wheels, and have not had problems since.
The strong 700c rims are: Velocity Dyad, Mavic A719, Salsa Delgado Cross, Sun RhynoLite. As to hubs - if you can afford Phil Wood, that's the gold standard, otherwise go with Shimano. For spokes, go with double butted - they build a stronger, more durable wheel because they flex a bit in the thin section
My best wheels, which came with a lifetime warranty from Peter White Cycles (one of the premier wheelbuilders in the US), is the Velocity Dyad built on Phil Wood standard touring hubs. I'm going into my 4th season with these wheels, and they have never required anything beyond the most minor truing. I also have a set that consists of the Salsa Delgado's built on Shimano XT hubs, which have held up well.
