It is possible to get the CPL with 190 hours part 141, but it is rare that people actually get it with minimum time. It is even harder to get hired as a commercial pilot with 190 hours.

If you go part 61 and feel competent to pass the check ride before 250 hours, start the training for your CFI. You can't take the checkride before you get your commercial liscence, but the advanced training will reduce the time to get ready for the CFI when you do go for it.

If you have a chance, try to get some training in a glider, both ground and flight. It gives you a different perspective on flying, and insights into aerodynamics that most power pilots are never taught. I don't remember if any glider flight time can count toward airplane ratings. Perhaps somebody else can answer that.
