The power provided by Strava is worthless unless you're climbing a hill. You don't need power to train though.
You should be fine with a Garmin HR strap and a speed/cadence sensor. You can use the speed/cad sensor on a trainer, and for many trainers you can also get a reasonable estimate of power based on your speed.
If you're on the trainer there are also PC applications (trainerroad.com, peripedal etc) that let you customize your workout, control videos and estimate power. They may have something for the iPhone as well but having a bigger screen to look at is nice.
