zeeman,
you'll learn plenty from a realtor that specializes in helping investors. especially if you're investing out of town. you need to find a good realtor in whatever area you're looking at. some of the questions you asked, like about using an attorney to close, are dependent on where you are closing your deal. i don't really know much about it, but i've heard that in some states you use an attorney, some places a title company. you need to talk to someone that is familiar with the laws and customs of your particular area. also, starting out, you don't usually know anyone. your realtor can link you to title companies, re attorneys, home inspectors, etc. then, you keep the ones you like, and network with them for other professionals you might need.
this site is great for the general knowledge you can get about almost anything. sometimes, you get lucky and one of the really knowledgeable posters hails from your state, and can give you info specific to your situation. regardless, anything you learn you need to doublecheck with local laws and regulations from your area...
