My advice would be to start attending matches other than your own match that you run and win. Get a feel for how the local "pros" are shooting and what you need to work on. If any of them offer some coaching on the side, book a day with them, otherwise, find a USPSA oriented instructor to get you started. As others have said, Ben Stoeger has a bunch of media on his youtube page, some are clips of his full classes, some are just rants. Filter out the good stuff (it's very good) and avoid the range politics and his content is terrific.
Once you know what do practice and how, dry fire 10-15 minutes a day. You don't need to spend 2 hours daily doing this. If you are gripping the gun hard and properly your hands will be sore after 15 minutes.
