Yes get new wheels. I was out for a century ride Sunday and passed a fellow walking his bike on the side of the road waiting for his wife to come pick him up. He had broken a spoke on his Mavic Ksyrium/Askium (can't remember which) wheels. He was just out for a day ride with no load, but he was probably 200 lbs or so. I had a standard spoke wrench with me, but couldn't help him. Given your size alone, you will break a spoke someday with those wheels.

I'd recommend hand built, 36 spoke, 14 guage/2.0mm, Ultegra level hubs. Also 25-28c tires at a minimum will help prevent pinch flats and dented rims. Carry a couple extra spokes, a spoke wrench, and a cassette tool. If you break a rear spoke, you can re-true the wheel until you get to a town where there's a bike shop or where you can borrow a wrench and improvise a chain whip to remove the cassette and replace the spoke.
