Jay, I think you are sincere, so I will answer your questions sincerely... but honestly, you need to get your hands on a book and read it.
Carry your gun on your person in a holster. Considering the size and weight of your gun, I suggest you consider getting a shoulder holster. Do not carry your gun off person. You will not have access to it when you need it, and the chance you leave it somewhere... in the bathroom, on a counter somewhere, in your car... goes up substantially.
Use the safety on your gun. If you are going to carry your gun cocked (and you should) it needs to be locked... otherwise you will accidentally shoot yourself or someone else. 1911's necessitate the use of the safety, and the fact your gun guy told you otherwise is everything you need to know to go get yourself a new gun guy.
