Question#1: if your pre-boil is lower than you want your mash efficiency is off and you can either add DME to the boil or boil longer to concentrate the wort to your desired OG but you'll get less beer.
Question#2up the water to 1.5qt/lb. be sure that you stir well as you add the grains and prevent dough balls which can effect efficiency as well.
For improving your efficiency check the quality of the crush and be sure to stir well when dough in and stir again half way. If batch sparging be sure to stir really well prior to draining the wort to knock the sugars and try to use 180-190F water for the sparge as well.
If you are not killing your own grains then ask the LHBS to crush twice or tighten the gap for you.
