Maggie, a couple things come to mind.
First of all a complete tune-up: distributor cap, rotor, plugs, wires. Air filter and possibly fuel filter.
These are normal things that have to be done anyway. If you bought the truck and it was not taken care of, you would have to do these anyways, I think you have already done a lot of this.
Next step would be to try a fuel additive, do a search on Seafoam. I have never used it, but everyone swears by it.
If that doesn't work you might need to check your throttle body and IAC valve. There are some adjustments there that will affect idle speed and starting. I assume your vehicle is not throwing any codes.
BTW, my vehicle always cranks longer hot, but never fails to start or stalls. But cranking a little longer hot is normal, the idle speed is lower and the fuel mixture is not enriched as much, takes longer to "catch".
