The Chart Supplement is not available in "as-printed" form in iFly. However, the data is parsed and is available on the Airport Info screen.
The TPPs are also not available in booklet form. Instead, tap an airport, and in the QuickView window, tap View Plates. You'll find all the arrivals, departures, and approaches in there, and an airport diagram if one exists.
For airports in your flight plan, you will also be able to insert the waypoints from departures, arrivals, and approaches by tapping the "Procedures" button and making the appropriate selections after that.
