Military Power, if you want to use a CLP, the answers are yes according to the advertising, yes if you like to use bore snakes and yes only because some guns may come dry or get dry in shipping and you need to field strip and look at the barrel and things before shooting. My PERSONAL practice is to strip, do a light quick cleaning, and run a new gun pretty wet with lube since the surfaces in contact will be roughest then, and I'm hoping the oil will carry away the tiny particles broken away or shaken loose by the wearing-in process. Sort of like the break-in oil in cars. Please note, I have no scientific studies to confirm my practice, I'm not an engineer, I'm not a gunsmith, and I'm sure somebody else does it differently and that works equally well.
