Without images, it is hard to know for sure what went wrong. But with your 17-55 f2.8 you should be able to make sharp enough photos for just about any purpose.
If on a tripod, make sure the IS is turned off. If the tripod is not sturdy at all, use mirror lock up too, as the lens is quite heavy and long.
f10 seems a little but too small, f5.6 should do fine usually. Good luck with what you want to accomplish.
