17-40 is a good value lens, not great sharpness at the wide end, good AF speed
50f1.4 is okay, not good at 1.4, not fast AF, not built very solid
Either 100 macro is excellent
I'd go with a 24-70f2.8 - you'll probably get a good used deal because the new one is coming out.
Excellent IQ, fast AF, f2.8 for lowlight or fast shutter speed, excellent build. A bit heavy.
Then add a 85f1.8 when you can afford it. Great for lowlight and portraits of the kiddies.
