Here is the chart for the CO2 pressure
I do my Hefe's at 3 volumes. As you can see, at room temp, you can't hit that at 30 psi. If you can put it in the fridge the whole time, you could do that at 30 psi for a couple of days, then turn it down to 18-20 PSI. But it takes 2-3 weeks to fully carb up, and you wouldn't hit that. I'm also wondering if the reason you are leaving it at room temp is to let it age a bit longer, since it is a young beer.
I don't do the shaking option,
but this may be your best bet if you want it so you can drink away your sorrows while watching the bills. (Big win today though). So I'd set it to 30 at room temp, lay it on its side, and roll it back and forth for a few minutes. Then keep it at 30 psi all week, and put it in your fridge, serve under 18 psi if you have a long enough (12-15 ft) of beer tube for serving.
Its a bit of a rush though. The goal would be to put it in a fridge after the beer has aged enough at 45ish degrees, set the pressure at 20-22 psi, and leave it for 3 weeks before you serve. So if your first kegging experience does not have the end results as you expected, thats why.
