The tutorials may all seem like different subjects, but they are really all aiming at the same goal. Try anything that jumps out at you, but have patience and don't get frustrated if it doesn't work right away.

Generally, you want to do a few basic things, no matter what.
Keep a dream journal and review it often to find dreamsigns.
Do Reality Checks throughout the day to increase your awareness.
Integrate some kind of Wake Back To Bed into your sleep schedule.

The trickier meditation-based tutorials, like WILD, should all be used in addition to these basic things.
