StarCraft 2 AI differences

Don't APM spam useless actions.

While lots of people on youtube will do this to appear better, no professional player does this. Often times jitters at the start of a match will cause them to select between multiple units but Starcraft does not register this as actions. During the course of battle you will see professional players microing units with a large number of clicks for a given move, or swap between a dozen different buildings to keep track of queues, or send new workers to mineral patches (no auto rally in SC1). This is not spam, every one of the actions has a directed purpose.

Additionally, Splitting your workers (having them divide to different patches at the beginning of a match) was necessary in Starcraft 1 as the AI was less intelligent. There have been studies in Starcraft 2 to show that the effects of this are below the margin for error. While many pro Starcraft 2 players still do this, it is hold over from Starcraft 1, not a necessary strategy.

There are a number of resources you can use to help your apm. My favorite is the SC2 Multitasking trainer map by Stet_TCL. You can find information on it here: http://www.teamliquid.net/forum/viewmessage.php?topic_id=124983

The design is to build an army to assault an enemy base while keeping a probe on an island alive through micromanagement and picking up a stranded high templar all in a time limit. It is VERY hard, but an excellent training resource.

I am not able to test it right now, but shouldn't double-clicking on the building select all similar buildings, and then right clicking on the location you want to rally do exactly what you want?

Alternatively selecting each building you want to set the same rally point holding shift should, afterwards again right klicking to the location.

Alternatively, you could add additional buildings to a control group later. Select the first building, then ctrl+#. Then select the next building, and shift+#. You can use shift+# to add additional items to any control group.
