Private orbital space voyaging, first...
...then, while private industry learns how to make that work, with a profit margin, the gov agencies can be pushing on to the moon. While that proceeds, researchers can be taking the lessons learned from that re-do of the space race, and figure out how we'll get to Mars.
Before all that, what we need is an inspired leadership - not only enough to resolve the criticisms of cranky congresspersons who didn't get a good parking spot fore the day, but as well, to inspire the engineers and the broader population not only to "play along", but to get it $(#$(#$ done.
I'm thinking of something in the spirit of John Kennedy. I'm not joking, there. It was his initial leadership that got the ball rolling, in the US. The appearance of competitive goading from the USSR of that day did add some fuel to the US national motivational tanks, as well. Then, after people applied themselves - being inspired to, rather than inspired to fumble fingers and turn the channel to watch the next episode of American Idol - rather than fumbling with bollocks, they got it done. and humankind made it to the moon. (with a whole lot more of significant details, occurring in the while, such that I've elided to the margins, here, for the sake of rhetorical brevity)
Vision and direction are, together, the first thing. Funding, the second. Engineering, the third.
Oh look, a new mayonnaise commercial.....
