What do players do to get super high APM? Like 300+ all game long, wtf is up with that.

When the c-shiftclick mineral gathering bug was still in I was at 400 during early game but I don't see what the top players do during the games to keep it so high?

Are there any specific things that boost efficiency that require high APM?

this is nada playing, it shows how the pros keep their apm up

Lots of players will cycle through their control groups to see when they have to make a new unit.

I.E. A terran has his command center on 4, barracks on 5, and factory on 6.

Terran will do 456456456 and when a unit is about to finish they will hit the control group and make something new. So for example: 456456454s5d,6t to make an SCV, marauder, and thor.

At the beginning of the game, it is almost entirely spam; however, its done to keep on pace. I typically start early game with overlord on 2, hatch on 3, and initial drones on 4(i later re-assign 4 to my queens). I will do 234234234234 while using my mouse to make boxes below my hatch repeatedly(habit from BW due to no auto-mine rally points) then after about 5-6 boxes I will right click two separate mineral patches. It helps with mouse accuracy and speed.

Don't worry about your APM too much. SC2 only requires about 150apm to play effectively, unless you plan on winning the GSL.
