Andrew: Some thoughts, take them for what they're worth, and consider the source...
Sounds like you're in need of some new challenges. Unfortunately, given your location, you'll probably have to travel some in order to find them. Is it feasible for you to bowl in any of the megabuck events, such as the Mini Eliminator, High Roller, TAC, or Super Hoinke? Or are there any similar events that might be closer to you?
Funny you should mention the ABC Masters. A friend of mine made the first cut. He's not a PBA member, and he doesn't have a coach, but when he's back home, he bowls in just about everything he can find. There's no substitute for tournament experience.
Best of luck to you with your game...and with the little one on the way.
