You really need to decide on if you want to be competitive in matches, or highly classified. There are a TON of GM shooters out there who get regularly spanked by A and M shooters because they just shot classifiers.
You then need to be honest about where your weaknesses are. Definitely get into an area match, take photos of the stages, and recreate the harder bits. Maybe your local club is GTG, maybe not, but a lot of local clubs don't really add the variability you see at the larger matches.
A good way to approach it in your first year, is train the skill dry fire, and evaluate your progress with live fire. You should be doing 10 - 20 reps dry for every one rep live fire, since so much of shooting at a high level is refined muscle memory. Add a lot of movement.
What really separates the top shooters from everyone else is their efficiency in moving through firing positions. Most guys can, in a year or two of hard pratcice, catch up to top shooters in things like draw time, reload time, splits, bill drill, etc. Thats not what wins matches (only classifiers). Matches are about getting very quickly to the different shooting positions, getting adequate hits, and getting to the next firing position.
