There's no doubt that a certain number of amateur-hour antics emanating from the White House have exacerbated the GOP's governing troubles. The fact that neither Bannon nor Priebus has any relevant background in executive branch management surely isn't helping here. But, fundamentally, when you elect an amateur president, you get an amateur-hour White House. Trump himself could step aside in favor of Mike Pence, a former governor of an actual state and a veteran Congress member, who would conduct himself in a professional manner. But short of that, there's not much one can really do here.
Meanwhile, Pence or anyone else in the job would struggle with the Republican legislative agenda for the fundamental reason that it doesn't make sense.
The Affordable Care Act promised to provide Americans with universal, comprehensive health insurance coverage. It brought us a lot closer to that goal, but it also fell short in a variety of ways. Republican spent years tapping into public frustration with the ways it fell short to drive anger at the law. But from day one, they have proposed replacing it with measures that would move us further from what voters want — covering fewer people, raising deductibles, making insurance less useful to the sick — rather than closer, in order to pursue a policy agenda of tax cuts on the rich that isn't even popular among rank-and-file GOP voters.
This bait-and-switch agenda is reasonably clever if you accept the key premise that Republicans must find some kind of way to advance an unpopular tax-cutting agenda. But it's objectively difficult to pull off because inability to communicate honestly about what you're doing undermines internal communication, and because the practical consequences of enacting an agenda that delivers the opposite of what was promised are inherently problematic.
To the extent that Trump has anything to do with these problems, it's that the intellectual and ideological shambles of modern conservatism made the Republican Party primary process more vulnerable to takeover by a mountebank like Trump than it should have been. But the shambles itself long predates Trump, and fixing it would require something much bigger than a staff shake-up.
