yeah you need to get this sorted before she gets any bigger. for the lead biting, if its a nylon lead then hold it with both hands with space in between, encourage he to bite it when she dose pull it sharply to the side so she gets a small burning sensation on he tongue. kinda like if you were to halve a rope pulled through your hands. she should find it uncomfortable and not want to take the lead in her mouth.
get her off the couch, let her up if she is going to be good and sit but not if she is going for your face. if she dose put her down make her go to a blanket or something in the corner of the room, don't let her sit at your feet unless she is behaving.
the pants, put her lead on and walk round the house or do whatever it is that attracts her to bite them. She she dose tug on her lead, one really hard correction is better than lots of little ones. you may feel guilty but she needs to know this is not acceptable.
she may just be a dog that doesn't want to be lifted, there is nothing wrong with that as long as you can pick her up for like the vets table or in an emergency. try ignoring her don't fuss over her as much, you might be babying her to much.
