Yeah there are, if you hit up YT and look for a race specific tutorial there will be loads. As a player this is what you want to do:
Get comfortable in a race.
Find a build that is very plain and practise it on custom maps with AI.
Play that thing inside out, learn keys, grouping, and always be hitting a time where you have the same amount of army/workers as the tutorial.
Hit the ladder and play that same build, lose/win, it don't matter.
Play it again. Get comfortable with it.
Keep playing the same, forget winning.
Before you know it APM has jumped 20, 30, 50.
Then go back and look at fresher/newer replays on YT.
As for what you want to be doing:
Always concentrate on your game, do not slip, don't cut, don't get greedy. -priority.
Once you have that under control, figure out what they are doing, or rather what can they be doing. It takes a lot of understanding of timing, resource of the other race, i.e. he's on 4 gas but you only see mineral tech, prepare for a heavy assault of high tech units, or learn to push out before he has the tech tree completed.
Most of all, watch your replays, be hard on yourself, did you constantly make workers? did you let the scout die without controlling it? Look for those things and fix it next game.
When WoL started I was plat, then I was gold, now I'm silver but this is mostly because I hardly get to play in a rhythm due to having a young kid. Practise and understand, and learn from mistakes. I'm almost the bottom of the scale and giving advice but there won't be many around to say I'm telling you incorrect skills to learn.
this should help out a bit, and best of luck to you:
