With just personal gear and no water, I would like to see that pack weight under 25#. You can save weight on clothing and raingear, really pay attention to weight on everything. Cut out things like an individual first aid kit, any eating equipment other than a plastic spoon and an empty cream cheese container for an eating bowl. The advice to go on a shakedown and leave anything that doen't get used is good.
When backpacking you have to really think about how to get the maximum utility from every item that each person carries. Be brutal; if it isn't absolutely needed, leave it at home.
