I do and recommend everything mentioned, but I also shoot "300" rounds. I am not a target archer really, but I have improved my shooting dice regularly scoring myself on the 300.
Get a NFAA 40 cm target face. It has a circle, and 4 outer rings. The center is worth 5 points, then 4, 3, 2. 1.
The round is 12 ends (rounds) of 5 arrows. All. 5's would be a 300 score. This is to be done at 20 yds, officially, but people do it at closer ranges to start.
I practice 3-4 times a week, but try to do 1 serious 300 round a week. Having a score is nice, tracks where you are at, and doesn't lie.
I prefer roving more than anything. But that 300 helps me alot
