As you mentioned re. lifting, you need to set some goals. By this, I don't mean "Someday, I'd like to shoot the FAST in 7 seconds" type goals.
I mean sit down and plan out what kind of shooting goals that you are interested in and capable of. Competition? Self defense? Both? Write that down. How much are you willing to spend in ammo and time to devote to improving and reaching your goals. Write that down. What obstacles will prevent you from reaching your goals? Write that down.
Once you have figured out the answers to the questions above, then you can work on setting realistic, short term (< 3 months) goals. Once you have these goals figured out, then you can pick out drills and tests to organize your practice sessions. Write them down in your range diary and follow the plan when you practice. Test yourself regularly and work on things that you are bad at.
By nature, I am not a goal setting/planning type of person. I'm a pretty Laissez-faire, "Whatever, Dude" kind of guy. And my shooting skills reflected that for many years. But once I got off my duff and did the hard mental work to evaluate and formulate my shooting goals, and structure my practice sessions, my progression was swift. Yours can be too.
None of this came out of my head, it's all from Lanny Bassham's book, With Wining In Mind.
In addition to the great drills found here, look at the handgun drills and handgun standards at

Pick and choose the ones that will help with your goals.
