One additional thing you might consider doing in this scenario is to active your ELT to give your exact position.
Same applies with an engine failure - manually activate your ELT sooner rather than later. That way they are on their way before you even hit the ground.
All assuming you have an onboard ELT of course (which we in the US have!)
Just remember that if you have an ELT that transmits on 121.5 (exclusively or in addition to 406 MHz), it will make communications at 121.5 virtually impossible. So if your emergency is being handled on 121.5 you will want to delay switching it on to the last possible moment. And you might want to advise ATC about it: "Off comms, switching on ELT" or something like that.
