I would sincerely investigate in the Universities that offer Project management. They will sit you down and explain every question under the sun to you. It its tool lenghtly to describe. Would not answer all your question anyway! My question to you, is why do you want to go into project management and leave the Architect world. This is a very demanding discipline and not for the timid. You must be making decisions and at times not be the most popular person in the room. I wish you luck, but please take my advice and invest in your self!!!
