im not a fit expert. (i know basics)
You should measure your inseam and multiply by .887 this should give you ball park on your saddle hight. I point this out because rider weight is distributed thru handlebars/seat/pedals if you put to much weight on your hands youll probably end up with a very soar back (putting more weight on your saddle would help a lot)
the seat seems low for the frame, if that quill stem came on the bike or was fitted for a taller rider your probably reaching too far. (adding to the back issue)
you can start researching fit on sheldon browns website (google it) its a very nice way to begin
also you can visit wrenchscience . com for a pretty nice fit calculator to find out your corect ball park reach
hybrids aren't designed to be sport oriented bikes, are more of a commuter/mup/do it all bike. A road bike that fits you can be very satisfying and comfortable ride.
hope this helps
