Just take a look at the vacuum hoses if they are cracked or very soft they should be replaced. If you have any doubt about a hose take it off block off one end use a rag over the other and blow through it if you hear air leaking then replace it.
Have you removed and cleaned out the IAC Valve. The valve may not be bad just carboned up and not openning or closing and cleaning it may fix you problem. It sounds like either a vacuum leak somewhere or the IAC.
