Welcome @gavin.brazg - I suggest to get started going old skool and simply performing your workout with a timer and pedalling harder or easier.
Look at your workout before you go ride and if you have 3 x 10 sst - you know to warm up for 30 minutes pedal in your sweet spot zones for 10 minutes, rest for 5 minutes and repeat. Ride in zone 2 until you get home or reach the end of the prescribed duration.
Once you get that down then you can bring in all the tech and that is 100% up to you - we just design the plans 
A wahoo or garmin bike computer is great to record your data. You can export your workouts to either an d follow along the plan.
You can get a team discount at Excel Sports for those bike computers, and smartTrainers
