Good Day - Here are my thoughts:
1. The trail is very well marked, with clear and consistent mile markers, as well as excellent signage at various trailheads. I am unaware of a Mickelson-specific phone app, however I use both MapMyRide and Cyclemeter on my rides - including when on the Mickelson. I recommend either, or any of the others readily available on the app store. You should not have any significant difficulty staying on the path. I do recommend studying the route beforehand, including the split near the 100.5 mile marker. While the reconnect at the Kirk Trailhead, one is steeper than the other.
2. The items listed are smart. Make sure you have a good phone charge as well, perhaps with an extra charger/cord. You will be going through some towns, and most of the trailheads should have water. I recommend a pannier for the items, either a rear one (you will need a rack for that), or one that will fit into the bike frame.
Also, mornings can be cool so layer work well.
I am heading out later this month and will revert back if I can think of anything else. It's a beautiful trail, and I think you all will love it.
