Ha, tbh I was once 'that guy' too. We all have to start somewhere, right?
As for oxygen-free transferring, you can first purge your keg (many of us fill it completely with sanitizer and use CO2 to push it out, effectively leaving very minimal residual O2 in the keg). Then you can connect your tubing from your racking cane to a quick-disconnect, and have the beer flow into the keg via the 'out' post (diptube). You'll have to either pop up the PRV and keep it open so that the air in the keg can escape as the beer fills it, or you can connect a gas QD to the gas post and let the air out that way.
Here's a pic to illustrate:
Purging the keg afterwards is still recommended.
If you really don't want the beer to touch O2, you can also get one of the carboy caps with 2 ports and use one for your racking cane, and the other to push CO2 into the carboy (and thus use the CO2 to push the beer out via the racking cane). I don't go this far, as I feel that the few minutes that the beer may have in contact with any O2 drawn into the carboy will be purged anyway. It's such a short period of time and I don't find the beer has a chance to absorb any O2 (though I'm sure it happens on a very small scale).
