Before you start a tune up, you might want to fix your actual issues. First clean your t/body and IAC, the 2 most common high idle problems, then replace your fuel filter and plan on replacing your fuel pump after verifying that you have no fuel pressure in the rail before trying to cold start it. There is a valve in the fuel pump that fails causing the gas/pressure to bleed off over night which then makes it hard to start. If you want to verify the pump issue, send me your number and I'll walk you thru what to do.
