B&H is a great online dealer. Readjust your budget and try to get the best lens that you can afford. Start with one, like a Canon 24-105 f4 as a walk around and then add high quality lenses down the road.
www.dpreviews.com provide very good in-depth reviews of almost all cameras and many lenses. I stick with Canon, but there are some very good independent lens makers, but you have to see reviews and actual results.
If you have to compromise on the camera or the lens, then do it with the camera body and own at least one very good lens and a 1.4 teleconverter.
