If you going to have fast 2.8 zoom in 17-50 range, you don't need 50 1.8.
It will be total waste of $100. Only those who ended up with Rebel kit lens might be interested to have at least one fast lens. With 2.8 and high ISO capabilities of 60D, practically, no reason for cheap 1.8 prime.
I'll recommend to skip as much plastic as possible including 55-250, the 70-200 F4 is well above this one for IQ and it works as very very good portrait and landscape lens as well.
You have do decide where is priority in portraits or macro. Then it would be 85 1.8 for portraits and Raynox macro lens to use same lens for macro. Or 100 2.8 for macro and portraits.
Get Canon flash, like 430 EX II which supports HSS, it makes huge difference for fast moving objects and to take portraits with wide aperture on bright day.
Skip on spare batteries for now. Canon makes good batteries which lasts for few days with thousands of pictures taken. New battery will hold the charge and capacity for about one year of daily use.
