No do not shave all the leaves off during budding. Thats done at harvest. Moderent prunning is ok though. Pull little shoots that would just waste energy.But don't take to many or any that are over 1". This will make you're main buds bigger and if you doit right you will increase your yeild. If you are starting right now and the plant has room to get possible 5 -7 foot tall then you may get bud in pounds. But you probably want a little topped plant. If you top it and let it grow until fall it'll yeild anywhere from6oz-3lb. It really depends on alot of variables but thats the range if done right.
