Good golly gosh, misinformation everywhere.
Wrong. Weight-training is important for functional strength and endurance in day-to-day repetitive tasks and becomes more important as you age in order to counteract age-induced muscular atrophy.
Rubbish. The only time cardio is useless if you are training for a specific high level event that requires high strength or power. People wanting to exercise for health and fitness should incorporate both endurance and resistance exercise into their programs, for the sake of variety if nothing else.
Muscle protein does not get “burned” as a substrate for energy production, except in cases of extreme starvation. The reason you don’t bulk up with endurance exercise as opposed to weights is because you are training completely different aspects of the muscle. Muscle responds to the demands you put on it. Lift weight = muscle growth due to hypertrophy of fibres, growth of new muscle and upregualtion of the fast myosin isoform and glycolytic enzymes. Endurance training = upregualtion of slow myosin isoform, increased expression of oxidative enzymes.
Wrong. Train for your needs. Please refrain from giving overgeneralised advice.
Ignore PW’s protocol out of hand. Exercise response is individualised and its pointless to tell people your program and except them to get any benefit out of it. Eg. I put on 20kg (~50lbs) by doing nothing more than bicep curls, tricep dips, push ups and situps. In contrast, a mate of mine does substantially more resistance training than me and never gains any weight.
Only consult sources endorsed by an authoritative body such as the American College of Sports Medicine (ACSM) or the Mayo clinic. Books published by Human Kinetics are also reliable.
The Recommended Quantity and Quality of Exercise for Developing and Maintaining Cardiorespiratory and Muscular Fitness, and Flexibility in Healthy Adults.
Read this. Its an ACSM position stand and should give you some guidelines. If you want more detailed advice, either consult one of the staff at a gym or similar. Or post here I can give you some advice on how to start out.

This one day I went to change my password, but being the clever chappy that I am, I accidently typed the new pw into the e-mail address bar and clicked submit, hence the slightly modified new user name. Go me and my awesome computer skills.
